Review request for Ambari and Vitalyi Brodetskyi.
Bugs: AMBARI-7812
https://issues.apache.org/jira/browse/AMBARI-7812
Repository: ambari
Description
-------
When running Flume Agent on Ambari installed cluster, the command aborts with
OutOfMemory, here is a sample run:
/usr/hdp/current/flume-client/bin/flume-ng agent -n agent -c
/usr/hdp/current/flume-client/conf -f
/grid/0/hadoopqe/tests/flume/conf/avro-memory-file_roll.properties
-Dflume.root.logger=DEBUG,console

I think the issue here is as we see in the console output that Flume Agent
complains that no JAVA_HOME is set so it picks up the java in the default path
which is /usr/bin/java.
# /usr/bin/java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-4)

As we see that it uses some 1.5.0 release of Java. We should have used the
installed JDK.
# /usr/jdk64/jdk1.7.0_67/bin/java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)
Basically we should set JAVA_HOME in $FLUME_CONF_DIR/flume-env.sh. In
gsInstaller install we append the following line to flume-env.sh.
export JAVA_HOME=<Installed Java Home>
