Suresh Srinivas updated HDFS-4979:
----------------------------------
Attachment: HDFS-4979.5.patch
Updated patch to fix failures and complete retry cache for all the following
operations:
*ClientProtocol*
* create()
* append()
* rename()
* concat()
* rename2()
* delete()
* saveNamespace() - this can be made idempotent, if writeLock is held in this
operation
* createSymlink()
* updatePipeline()
* createSnapshot()
* deleteSnapshot()
* renameSnapshot()
* mkdirs() - was incorrectly marked as idempotent
*NamenodeProtocol*
* startCheckpoint()
* endCheckpoint()
* commitBlockSynchronized()
*DatanodeProtocol*
* blockReceivedAndDeleted()
Note that mkdirs() was previously incorrectly marked as idempotent. I plan on
removing the idempotent annotation for that method in HDFS-4974.
