Amar Kamat updated MAPREDUCE-2777:
----------------------------------
Attachment: mapreduce-2777-v1.3.patch
Attaching a patch that backports the MAPREDUCE-220 and MAPREDUCE-2469 features
to the hadoop-0.20-security branch. MAPREDUCE-220 and MAPREDUCE-2469 have
dependencies which also got selectively backported. Here is the list of JIRA's
that got backported:
MR-220, MR-1201, MR-1762, MR-1218 & MR-2469. I have resolved most of the hunks
w.r.t parameter naming, missing APIs and missing backports (e.g GC_TIME_MILLIS
counters etc).
We have tested this patch at scale and also benchmarked this patch for
regressions. It seems that the overhead is negligible and the newly added
counters are correctly captured and recorded.
