Subject [jira] [Updated] (HDFS-3412) Fix findbugs warnings in auto-HA branch
Date Sun, 13 May 2012 02:24:48 GMT

     [ https://issues.apache.org/jira/browse/HDFS-3412?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated HDFS-3412:
------------------------------

    Attachment: hdfs-3412.txt

- adds the generated protobufs to findbugs exclude
- adds some more synchronization in ZKFC to avoid "inconsistent synchronization" findbugs
- changes ZKFC to take its configuration and target in the constructor, rather than relying
on post-constructor "setConf()". This way these fields can be final, and we don't have to
synchronize to access them.

I ran the ZKFC tests under jcarder to verify this didn't introduce new potential deadlocks.

> A few minor findbugs warnings snuck in. Nothing looks like a real bug, but we should
fix before merging.
