Improve Error Handling in Local Directory Feeds This change improves handling of two error types for filesystem based feeds. The first one is the handling of IO Errors which causes the input stream to be closed, and the second one is reacting to missed filesystem events. In both cases, we scan the directory and compare it with the history we have in order to resume from where we last left off. In addition, this change includes some refactoring in external data. Particularly, we get rid of the stream provider layer and instead, stream factories create input streams directly. This is consistent with record reader factories which create readers directly without reader providers.

##Building AsterixDB
To build AsterixDB from source, you should have a platform with the following:
Additionally to run all the integration tests you should be running sshd locally, and have passwordless ssh logins enabled for the account which is running the tests.
Instructions for building the master:
Checkout Hyracks master:
$git clone https://github.com/apache/incubator-asterixdb-hyracks.git
Checkout AsterixDB master:
$git clone https://github.com/apache/incubator-asterixdb.git
Build and install Hyracks master to maven local repo:
$cd hyracks $mvn clean install -DskipTests
Build AsterixDB master:
$cd ../asterixdb $mvn clean package -DskipTests
##Running AsterixDB (on your machine from your build) Here are steps to get AsterixDB running on your machine:
Create a directory as the home for AsterixDB installer program, i.e., managix:
$mkdir ~/managix
Copy AsterixDB binary artifact into the installer directory and unzip it:
$cp asterix-installer/target/asterix-installer-*-binary-assembly.zip ~/managix/ $cd ~/managix $unzip asterix-installer-*-binary-assembly.zip
Configure the installer:
$bin/managix configure
Validate if the computer environment is suitable:
$bin/managix validate
Create and start your instance:
$bin/managix create -n test -c clusters/local/local.xml
Good to go and run queries in your browser at:
http://localhost:19001

##Documentation
AsterixDB's official documentation resides at [https://ci.apache.org/projects/asterixdb/index.html] (https://ci.apache.org/projects/asterixdb/index.html). This is built from the maven project under asterix-doc/ as a maven site. The documentation on the official website refers to the most stable build version, so for pre-release versions one should refer to the compiled documentation.
