Ran hod after applying patch with follwoing options -:
hod -c conf/hodrc0.16 -b 4 -o "allocate clusterDir1 3"
--gridservice-mapred.envs='HADOOP_OPTS=-Dmy.env\=\"Hello\,World\:Test\/test1\;tt\"\
-Xms512m\ -XX\:\-UseParallelGC
-XX\:\-RelaxAccessControlCheck,HADOOP_HEAPSIZE=2048,HADOOP_ROOT_LOGGER=DEBUG\,console'
--gridservice-hdfs.envs="HADOOP_OPTS=-Dmy.env\=\'World\:Test\'\
-Dmy.env2\=\'hodtest/HOD\'\ -XX\:\+MaxFDLimit -
XX\:\+UseBoundThreads
-XX\:\+UseTLAB,HADOOP_CLASSPATH=/home\:/proc,HADOOP_HEAPSIZE=2048,HADOOP_ROOT_LOGGER=DEBUG\,console"
Also tried it by setting value in hodrc.
Note--: If in hodrc some value of key=value params contains ';' then value from
';' afterwards will be ignored. Same thing works from commandline.
Tried with bot hadoop 0.16 and hadoop 0.15
Also ran smoke test successfully with static dfs

> Key: HADOOP-2766
> URL: https://issues.apache.org/jira/browse/HADOOP-2766
> Project: Hadoop Core
> Issue Type: Bug
> Components: contrib/hod
> Affects Versions: 0.16.0
> Reporter: Hemanth Yamijala
> Assignee: Vinod Kumar Vavilapalli
> Priority: Critical
> Attachments: hadoop-2766
>
>
> For purposes of performance tuning it should be possible to set some
> environment variables that Hadoop honors before launching the Hadoop daemons.
> For e.g. to set the heap size of the JVM, we should set the HADOOP_HEAPSIZE
> variable. These can be configured through hodrc using the
> gridservice-mapred.envs environment variable. This works for everything
> *except* HADOOP_OPTS, which is also useful, for e.g. to pass in Garbage
> collection parameters to the JVM, like -XX:+UseParallelGC. This is because
> HOD tries to set HADOOP_OPTS from the gridservice-mapred.java-opts variable,
> but it does not read the java-opts variable anywhere properly.
