Junping Du commented on MAPREDUCE-6068:
---------------------------------------
Forget to mention, there is still another place in Merger.java that could over the limit:
{code}
if (totalBytes != 0)
mergeProgress.set(totalBytesProcessed * progPerByte);
else
mergeProgress.set(1.0f); // Last pass and no segments left - we're done
{code}
[~decster], do you think we should update here also?
