hdfs Jenkins build fails due to findbugs not finishing

[Ted Yu <yu...@gmail.com>]

Hi,
You may have noticed the following in recent hdfs Jenkins builds:

[INFO] ------------------------------------------------------------

[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
