---------------------------------
Summary: Update findbugsExcludeFile.xml to reflect
Key: HDFS-4031
URL: https://issues.apache.org/jira/browse/HDFS-4031
Project: Hadoop HDFS
Issue Type: Sub-task
Components: name-node
Affects Versions: 2.0.0-alpha
Reporter: Eli Collins
Assignee: Eli Collins
Findbugs 2 warns about some volatile increments (VO_VOLATILE_INCREMENT) that
unlike HDFS-4029 and HDFS-4030 are less problematic:
- numFailedVolumes is only incremented in one thread and that access is
synchronized
- pendingReceivedRequests in BPServiceActor is clearly synchronized
It would be reasonable to make these Atomics as well but I think they're uses
are clearly correct so figured for these the warning was more obviously bogus
and so could be ignored.
There's also a SE_BAD_FIELD_INNER_CLASS warning (LocalDatanodeInfo's anonymous
class is serializable but it is not) in BPServiceActor is OK to ignore since we
don't serialize LocalDatanodeInfo.
