------------------------------------
Summary: When an ApplicationMaster restarts, it restarts the
launcher job: DistCp followup
Key: OOZIE-1728
URL: https://issues.apache.org/jira/browse/OOZIE-1728
Project: Oozie
Issue Type: Sub-task
Affects Versions: trunk
Reporter: Robert Kanter
Assignee: Robert Kanter
In doing OOZIE-1722, we had not not add support for the DistCp action because
there wasn't a good clean way to set the {{mapreduce.job.tags}} property on the
job launched by DistCp that would work between all versions of Hadoop.
The best solution would be to switch our version of Hadoop 1 to Hadoop 1.2.1
(OOZIE-1613), which would make DistCp v2 available in Hadoop 1. The signatures
of DistCp's constructor (where we can pass the tags property in a
Configuration) should then be same. We can then duplicate what
DistCp.main(...) does.
A more immediate solution would involve some ugly reflection based on different
versions of Hadoop.
