getCorruptFiles() should double check blocks that are not really corrupted
--------------------------------------------------------------------------
Key: HDFS-1259
URL: https://issues.apache.org/jira/browse/HDFS-1259
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 0.22.0
Reporter: Rodrigo Schmidt
Fix For: 0.22.0
the getCorruptFiles() api is based on blocks that are in the queue of
under-replicated blocks. However, this queue might be outdated and report
blocks that are safe, specially during restarts when block reports might get
delayed.
getCorruptFiles() should double check if the block is really corrupted based on
blocksMap before reporting it.
