Delete the directory /foo/test > 5. wait till checkpoint or do saveNameSpace > 6. restart NN. > NN enters to safemode. > Analysis: > Snapshot nodes loaded from fsimage are always complete and all blocks will be > in COMPLETE state. > So when the Datanode reports RBW blocks those will not be updated in > blocksmap. > Some of the FINALIZED blocks will be marked as corrupt due to length mismatch. -- This message was sent by Atlassian JIRA (v6.1#6144)
