Subject TestReduceFetch fails on 64 bit java on branch 0.20 and y! hadoop 0.20.1
Date Wed, 05 Aug 2009 00:19:25 GMT

With JAVA_HOME set to 64 bit version of jvm,   "ant  test -Dtestcase=TestReduceFetch" fails
with error message

--
junit.framework.AssertionFailedError: Expected at least 1MB fewer bytes read from local (21135390)
than written to HDFS (21012480)
        at org.apache.hadoop.mapred.TestReduceFetch.testReduceFromPartialMem(TestReduceFetch.java:133)
...



The same test succeeds with 32 bit jvm.  java version "1.6.0_07" is used on both the cases.

This error is reproducible in both hadoop0.20 and hadoop0.20.1 (yahoo's release)

Anybody seen this issue?

Thanks
Rama
