Shwetha G S commented on OOZIE-2129:
------------------------------------
Few things, I have fixed them. Can you test to see if its ok?
1. CHILD_MAPREDUCE_JOB_TAGS should be defined just once
2. Simplified LauncherMapper.propagateToHadoopConf()
> Duplicate child jobs per instance

> OOZIE-1722 ensures that child job is killed at launcher restart. But this
> doesn't work for java actions as the tag is not passed to the child job.
> In case of coord action rerun, new workflow is created and hence new tag. So,
> it doesn't ensure old child job is killed at launcher start
