Mike Liddell updated HADOOP-10728:
----------------------------------
Attachment: HADOOP-10728.2.patch
new patch: HADOOP-10728.2.patch
- moved finalizer from BandwidthGaugeUpdater to AzureNativeFileSystem. (it
would logically be better on the former, but those instances are still attached
to GC-roots when a filesystem instance gets GCed. This was root cause of
testFinalizerThreadShutdown failure.)
- revised testFinalizerThreadShutdown to accurately track thread counts.
- fixed pom.xml to include the metrics configuration file for testing
(we now include * from src/test/resources)
- apache headers added to all files
- javadoc issues fixed.
- findbugs issues fixed.
- minor tweak to README.txt
- minor tweak to .gitignore
