[jira] Created: (HADOOP-1264) OutOfMemoryError while running sort
example
OutOfMemoryError while running sort example
-------------------------------------------
Key: HADOOP-1264
URL: https://issues.apache.org/jira/browse/HADOOP-1264
Project: Hadoop
Issue Type: Bug
Components: examples, mapred
Affects Versions: 0.12.3
Environment: Java 1.6.0_01, EC2 cluster with one slave (Linux domU-12-31-33-00-02-5A 2.6.16-xenU #1 SMP Thu Nov 30 13:48:50 SAST 2006 i686 athlon i386 GNU/Linux)
Reporter: Tom White
The problem is reproducible, and I get this stacktrace:

Devaraj Das commented on HADOOP-1264:
-------------------------------------
Although I don't know what value is mapred.child.java.opts configured to, could you please try increasing that to something like -Xmx512m?

[jira] Resolved: (HADOOP-1264) OutOfMemoryError while running sort

Tom White resolved HADOOP-1264.
-------------------------------
Resolution: Fixed
Setting mapred.child.java.opts to -Xmx512m resulted in no failures. Thanks Devaraj!

Tom White commented on HADOOP-1264:
-----------------------------------
I'm sorting data generated using random writer, like so
bin/hadoop jar hadoop-0.12.3-examples.jar randomwriter rand
bin/hadoop jar hadoop-0.12.3-examples.jar sort rand rand-sort.
Most of the maps succeed, but a few always fail with the above exception.

Tom White commented on HADOOP-1264:
-----------------------------------
Deveraj, thanks for the suggestions. I am using the default settings:
mapred.child.java.opts = -Xmx200m
io.sort.mb = 100
I'll try again with mapred.child.java.opts as you suggest.
