HDFS allows deletion of file while it is stil open
--------------------------------------------------
Key: HADOOP-3627
URL: https://issues.apache.org/jira/browse/HADOOP-3627
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.19.0
Reporter: Lohit Vijayarenu
This was a single node cluster, so my DFSClient was from same machine. In a
terminal I was writing to a HDFS file, while on another terminal deleted the
same file. Deletion succeeded, and the write client failed. If the write was
still going on, then the next block commit would result in exception saying,
the block does not belong to any file. If the write was about to close, then we
get an exception in completing a file because getBlocks fails.
Should we allow deletion of file? Even if we do, should the write fail?
