So, I have not yet checked it in. If you run a SecondaryNameNode with this patch against a NameNode that does not have this patch, then checkpointing will fail. > SecondaryNamenode fails to checkpoint because namenode fails with CancelledKeyException > --------------------------------------------------------------------------------------- > > Key: HDFS-1024 > URL: https://issues.apache.org/jira/browse/HDFS-1024 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 0.20.1, 0.20.2, 0.20.3, 0.21.0, 0.22.0 > Reporter: dhruba borthakur > Assignee: Dmytro Molkov > Priority: Blocker > Fix For: 0.22.0 > > Attachments: HDFS-1024.patch, HDFS-1024.patch.1, HDFS-1024.patch.1-0.20.txt > > > The secondary namenode fails to retrieve the entire fsimage from the Namenode. It fetches a part of the fsimage but believes that it has fetched the entire fsimage file and proceeds ahead with the checkpointing.
