Konstantin Shvachko commented on HDFS-4849: ------------------------------------------- The first formatting change is in the code adjacent to the one I modified. Couldn't resist aligning it correctly. The path goes to branch-2 as well, so it will not lead to diversion in formatting. The second is formally a replacement of a line with two spaces with a new method surrounded by empty lines, not just a whitespace change. If you feel strong I can revert the alignment, but would rather commit as such. Test failures were because of: TestBlocksWithNotEnoughRacks - HDFS-3538 TestQuorumJournalManager - HDFS-4899 > Idempotent create and append operations. > ---------------------------------------- > > Key: HDFS-4849 > URL: https://issues.apache.org/jira/browse/HDFS-4849 > Project: Hadoop HDFS > Issue Type: Improvement > Components: namenode > Affects Versions: 2.0.4-alpha > Reporter: Konstantin Shvachko > Assignee: Konstantin Shvachko > Attachments: idempotentCreate.patch, idempotentCreate.patch > > > create, append and delete operations can be made idempotent. This will reduce > chances for a job or other app failures when NN fails over. -- This message is automatically generated by JIRA.
