FYI, I've updated most Apache Hadoop builds on Hudson: https://hudson.apache.org/hudson/view/G-L/view/Hadoop/
1) updated email notification of build failure to include test failures and less console log 2) added common, MR, and HDFS builds for 0.22 branch (polls twice a day for changes) 3) made build parameters and commitBuild.sh script usage more consistent I also killed lots of rogue processes on the build machines and cleaned out /tmp on them. Looks like lots of tests are now writing to /tmp :-( Hard to believe that some builds haven't passed in over 6 months! Fixing HDFS-1502 should help. Also, looks like org.apache.hadoop.mapreduce.security.TestUmbilicalProtocolWithJobToken will require some kerberos setup to pass. Perhaps it needs to be conditional on having the right environment.
