Add minicluster config as hadoop-site.xml for testcases
--------------------------------------------------------
Key: OOZIE-802
URL: https://issues.apache.org/jira/browse/OOZIE-802
Project: Oozie
Issue Type: Bug
Components: tests
Affects Versions: 3.2.0
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
Priority: Critical
Fix For: 3.2.0
in MR2 (Hadoop 0.23) the configuration used by a client to submit jobs to the
cluster is used to configure the AM.
Currently this configuration is whatever has been set in hadoop-conf/ which is
minimal (setting yarn framework).
A problem arises in how AM and HS communicate to each other info a about a job
(via HDFS), AM using default conf values writes to /tmp while HS started by
minicluster looks in target/test-dir thus producing random failures. Random
because if the AM is still alive when the client checks for the job, the AM
gives the info correctly, but if the AM is gone the HS does not know about the
job.
We should seed the configuration of minicluster as the hadoop-conf/ used by the
testcases.
