Jeff Zhang commented on TEZ-1852:
---------------------------------
[~hitesh], it is the same if TEZ_RUNTIME_OPTIMIZE_LOCAL_FETCH is not set to true
> WordCount in local mode hangs in shuffle phase
> ----------------------------------------------
>
> Key: TEZ-1852
> URL: https://issues.apache.org/jira/browse/TEZ-1852
> Project: Apache Tez
> Issue Type: Bug
> Reporter: Jeff Zhang
> Priority: Critical
>
> WordCount hangs at the progress of 50%, it looks like something wrong in the
> shuffle phase. [~pramachandran], could you take at look at this ? I remember
> you had fixed this issue before. But now it comes out again, I verify that it
> works in 0.5.1, but it doesn't work starting from 0.5.2.
