Sandy Ryza created MAPREDUCE-5008:
-------------------------------------
Summary: Merger progress miscounts with respect to EOF_MARKER
Key: MAPREDUCE-5008
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5008
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 2.0.3-alpha
Reporter: Sandy Ryza
After MAPREDUCE-2264, a segment's raw data length is calculated without the
EOF_MARKER bytes. However, when the merge is counting how many bytes it
processed, it includes the marker. This can cause the merge progress to go
above 100%.
Whether these EOF_MARKER bytes should count should be consistent between the
two.
