Vinay created HADOOP-10071:
------------------------------
Summary: under construction files deletion after
snapshot+checkpoint+nn restart leads nn safemode
Key: HADOOP-10071
URL: https://issues.apache.org/jira/browse/HADOOP-10071
Project: Hadoop Common
Issue Type: Bug
Reporter: Vinay
1. allow snapshots under dir /foo
2. create a file /foo/test/bar and start writing to it
3. create a snapshot s1 under /foo after block is allocated and some data has
been written to it
4. Delete the directory /foo/test
4. wait till checkpoint or do saveNameSpace
5. 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.
