Subject hdfs Jenkins build fails due to findbugs not finishing
Date Tue, 29 Jul 2014 14:48:20 GMT
Hi,
You may have noticed the following in recent hdfs Jenkins builds:

[INFO] ------------------------------------------------------------
------------
[ERROR] Failed to execute goal

[ERROR] -> [Help 1]

Looking at https://builds.apache.org/job/Hadoop-Hdfs-trunk/1819/consoleFull
:

Currently we have:

export MAVEN_OPTS=-Xmx2048m


Should the value of 2048m be increased ?

Cheers
