> 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
> Assignee: Sandy Ryza
> Attachments: MAPREDUCE-5008-branch-1.patch, MAPREDUCE-5008.patch,
> MAPREDUCE-5008.patch

>
> 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.
> This a JIRA instead of an amendment because MAPREDUCE-2264 already went into
> 2.0.3.
