Enis Soztutar commented on HADOOP-3950:
---------------------------------------
TestMapRed passes after HADOOP-3946, but TestMiniMRDFSSort fails for me.
I tracked down the issue, which seems to be due to the call to
{{JobClient.getClusterStatus().getTaskTrackers()}} returns 0, which in turn
causes the RandomWriter to run with 0 maps.
I suspect the tasktracker has not finished its first heathbeat, so a call to
getTaskTrackers() returns 0. I will look into it.
> TestMapRed and TestMiniMRDFSSort failed on trunk
