-
-         $ managix help -cmd create
-         Creates an AsterixDB instance with a specified name. Post creation, the instance is in ACTIVE state,

+    -n Name of the AsterixDB instance.
+    -c Path to the cluster configuration file
 
 We shall now use the `create` command to create an AsterixDB instance by the name "my_asterix". In doing so, we shall use the cluster configuration file that was auto-generated by Managix.
 
-
-         $ managix create -n my_asterix -c clusters/local/local.xml
+    $ managix create -n my_asterix -c clusters/local/local.xml

 Managix associates a working directory with an AsterixDB instance and uses this directory for transferring binaries to each node. If there is a directory that is readable by each node, Managix can use it to place binaries that can be accessed and used by all the nodes in the AsterixDB set up. A network file system (NFS) provides such a functionality for a cluster of physical machines so that a path on NFS is accessible from each machine in the cluster.  In the single-machine set up described above, all nodes correspond to a single physical machine. Each path on the local file system is accessible to all the nodes in the AsterixDB setup and the boolean value for NFS above is thus set to `true`.
 
 ### Managix Configuration ###
 Managix allows creation and management of multiple AsterixDB instances and uses Zookeeper as its back-end database to keep track of information related to each instance. We need to provide a set of one or more hosts that Managix can use to run a Zookeeper instance. Zookeeper runs as a daemon process on each of the specified hosts. At each host, Zookeeper stores data under the Zookeeper home directory specified as part of the configuration. The following is an example configuration `$MANAGIX_HOME/conf/managix-conf.xml` that has Zookeeper running on the localhost (127.0.0.1) :
 
-
-        <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
-        <configuration xmlns="installer">
-            <zookeeper>
-                <homeDir>/home/joe/asterix/.installer/zookeeper</homeDir>
-                <clientPort>2900</clientPort>
-                <servers>
-                    <server>127.0.0.1</server>
-                </servers>
-            </zookeeper>
-        </configuration>
+    <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
+    <configuration xmlns="installer">
+        <zookeeper>
+            <homeDir>/home/joe/asterix/.installer/zookeeper</homeDir>
+            <clientPort>2900</clientPort>
+            <servers>
+                <server>127.0.0.1</server>
+            </servers>
+        </zookeeper>
+    </configuration>
 
 It is possible to have a single host for Zookeeper. A larger number of hosts would use Zookeeper's replication and fault-tolerance feature such that a failure of a host running Zookeeper would not result in loss of information about existing AsterixDB instances.

-
-        machineA> ssh-keygen -t rsa -P ""

-
-        machineA> ssh 127.0.0.1

 ### Step (2): Define the AsterixDB cluster ###
 
 We first log into the master machine as the user "joe". On this machine, download Managix from [here](http://asterixdb.ics.uci.edu/download.html) (save as above), then do the following steps similar to the single-machine case described above:
 
-
-        machineA> cd ~
-        machineA> mkdir asterix-mgmt
-        machineA> cd asterix-mgmt
-        machineA> unzip  <path to the Managix zip bundle>
+    machineA> cd ~
+    machineA> mkdir asterix-mgmt
+    machineA> cd asterix-mgmt
+    machineA> unzip  <path to the Managix zip bundle>
 
 Note that it is recommended that MANAGIX_HOME is not located on a network file system (NFS). Managix creates artifacts/logs that are not required to be shared. Any overhead
 associated with creating artifacts/logs on the NFS should be avoided.
 
 We also need an AsterixDB configuration XML file for the cluster.  We give the name to the cluster, say, "rainbow".  We create a folder for the configuration of this cluster:
 
-
-        machineA> mkdir asterix-mgmt/rainbow_cluster
-
+    machineA> mkdir asterix-mgmt/rainbow_cluster
 
 For this cluster we create a configuration file `$MANAGIX_HOME/rainbow_cluster/rainbow.xml`.  The following is a sample file with explanation of the properties:
 
-        <cluster xmlns="cluster">
+    <cluster xmlns="cluster">
 
-          <!-- Name of the cluster -->
-          <name>rainbow</name>

 As stated before, each of the above properties can be defined at the cluster level, in which case it applies to all the nodes in the system.  Each property can also be defined at a node level.
 
 Once we have formed the cluster XML file, we can validate the configuration by doing the following:
 
-        managix validate -c rainbow_cluster/rainbow.xml
+    managix validate -c rainbow_cluster/rainbow.xml
 
 This will verify the contents of the file, and also attempt to ssh to each node in the cluster to ensure that password-less SSH is configured correctly. You may see output like
 
-        The authenticity of host '192.168.100.1 (192.168.100.1)' can't be established.

 ##### Stop Command #####
 The `stop` command can be used for shutting down an AsterixDB instance. After that, the instance is unavailable for executing queries. The usage can be looked up by executing the following.
 
+    $ managix help -cmd stop
 
-         $ managix help -cmd stop
-        
-         Shuts an AsterixDB instance that is in ACTIVE state. After executing the stop command, the AsterixDB instance transits
-         to the INACTIVE state, indicating that it is no longer available for executing queries.
-        
-         Available arguments/options
-         -n name of the AsterixDB instance.

 The `start` command starts an AsterixDB instance that is in the INACTIVE state. The usage can be looked up by executing the following:
 
+     $ managix help -cmd start
 
-         $ managix help -cmd start
-

 ##### Backup Command #####

 We need to provide a path to a backup directory on the local file system. The backup directory can be configured be editing the Managix configuration XML, found at `$MANAGIX_HOME/conf/managix-conf.xml`.

 Prior to taking a backup of an AsterixDB instance, it is required for the instance to be in the INACTIVE state. We do so by using the `stop` command, as shown below:
 
-
-        $ managix stop -n my_asterix
-          INFO: Stopped AsterixDB instance: my_asterix
+    $ managix stop -n my_asterix

 We can now take the backup by executing the following:

 *Configuring backup on an HDFS instance*
 
 To configure a backup to be taken on an HDFS instance, we need to provide required information about the running HDFS instance.  This information includes the HDFS version and the HDFS url.  Simply edit the Managix configuration file and provide the required information.
 
-
-        <backup>
-           <backupDir>Provide path to the backup directory here</backupDir>
-           <hdfs>
-               <version>0.20.2</version>

+           <url></url>
+       </hdfs>
+    </backup>
 
 A sample output when a backup is taken on an HDFS is shown below:
 
-
-        $ managix backup -n my_asterix
-          INFO: my_asterix backed up 1_Fri Mar 08 17:10:38 PST 2013 (HDFS)

+      INFO: my_asterix backed up 1_Fri Mar 08 17:10:38 PST 2013 (HDFS)
 
 Each time we take a backup,  we are provided with a unique id  (a monotonically increasing value starting with 0).  This id is required when we need to restore from a previously taken backup. Information about all available backup snapshots can be obtained by using the `describe` command in the admin mode, as shown below:

 ##### Question #####
 Do I need to create all the directories/paths I put into the cluster configuration XML ?
 
 ##### Answer #####
-Managix will create a path if it is not existing. It does so using the user account mentioned in the cluster configuration xml. 
-Please ensure that the user account has appropriate permissions for creating the missing paths.

 ##### Question #####
 Should MANAGIX_HOME be on the network file system (NFS) ?
 
 ##### Answer #####
-It is recommended that MANAGIX_HOME is not on the NFS. Managix produces artifacts/logs on disk which are not required to be shared.
