-------------------------------------------
Summary: Maps hitting IndexOutOfBoundsException for higher values
of mapreduce.task.io.sort.mb
Key: MAPREDUCE-5031
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5031
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.5, 2.0.3-alpha
Reporter: Karthik Kambatla
Assignee: Karthik Kambatla
While trying to reproduce MAPREDUCE-5028 on trunk, ran into what seems to be a
different issue. To reproduce:
Psuedo-dist mode: mapreduce.{map,reduce}.memory.mb=2048,
mapreduce.{map,reduce}.java.opts=-Xmx2048m, mapreduce.task.io.sort.mb=1280
The map tasks fail with the following error:
