Rajesh Balamohan updated MAPREDUCE-5787:
----------------------------------------
Attachment: MAPREDUCE-5787-2.4.0-v7.patch
Addressed Vinod's concern on increased in memory due to mapOutputFileName and
IndexRecord. It is possible to configure the cache via
"mapreduce.shuffle.mapoutput-info.meta.cache.size". (default value is 1000).
String & locaDirAllocator computations will be carried out twice if number of
mapId goes past this limit.
> Modify ShuffleHandler to support Keep-Alive
