Ted Yu commented on HBASE-8258:
-------------------------------
bq. it will change underneath us and cause us pain
As I said above, 0.95 needs a stable hadoop 2 release (2.0.4-alpha).
For trunk, building against SNAPSHOT artifacts would allow us to find the
problem much sooner. If I understand Roman's point of view correctly, he wants
to discover regression in upstream project in a similar way.
bq. but doesn't get down to which particular variables are important.
One such config param is YarnConfiguration.IS_MINI_YARN_CLUSTER which must be
set true in order for MiniMRCluster to work.
See YARN-129
bq. Should it get folded in to all them?
Can you explain folding a little bit ?
bq. we should make them clearer for the next person.
Agreed. Will add comment once solution is finalized.
