> 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.
