When namenode goes down while checkpointing and if is started again subsequent
Checkpointing is always failing
--------------------------------------------------------------------------------------------------------------
Key: HDFS-1981
URL: https://issues.apache.org/jira/browse/HDFS-1981
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.23.0
Environment: Linux
Reporter: ramkrishna.s.vasudevan
Fix For: 0.23.0
This scenario is applicable in NN and BNN case.
When the namenode goes down after creating the edits.new, on subsequent restart
the divertFileStreams will not happen to edits.new as the edits.new file is
already present and the size is zero.
so on trying to saveCheckPoint an exception occurs
2011-05-23 16:38:57,476 WARN org.mortbay.log: /getimage: java.io.IOException:
GetImage failed. java.io.IOException: Namenode has an edit log with timestamp
of 2011-05-23 16:38:56 but new checkpoint was created using editlog with
timestamp 2011-05-23 16:37:30. Checkpoint Aborted.
This is a bug or is that the behaviour.
