Hi Gopal, Since this jira is resolved, I cloned the master branch, compiled and used the binaries (0.9 snapshot version of tez).
I tried running the shuffle hash join with auto reducer parallelism again. But, it didn't seem to take effect. With merge join and auto reduce parallelism on, number of reducers drops from 1009 to 337, but didn't see that change in case of shuffle hash join .Should I be doing something more ?
