Hudson commented on HDFS-2766: ------------------------------ Integrated in Hadoop-Hdfs-HAbranch-build #44 (See [https://builds.apache.org/job/Hadoop-Hdfs-HAbranch-build/44/]) HDFS-2766. Test for case where standby partially reads log and then performs checkpoint. Contributed by Aaron T.

Myers > Attachments: HDFS-2766-HDFS-1623.patch, HDFS-2766-HDFS-1623.patch > > > Here's a potential bug case that we don't currently test for: > - SBN is reading a finalized edits file when NFS disappears halfway through > (or some intermittent error happens) > - SBN performs a checkpoint and uploads it to the NN > - NN receives a checkpoint that doesn't correspond to the end of any log > segment > - Both NN and SBN should be able to restart at this point. -- This message is automatically generated by JIRA.
