------------------------------------------
Summary: Add DataNode support for mlock and munlock
Key: HDFS-5050
URL: https://issues.apache.org/jira/browse/HDFS-5050
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Colin Patrick McCabe
Add DataNode support for mlock and munlock. The DataNodes should respond to
RPCs telling them to mlock and munlock blocks. Blocks should be uncached when
the NameNode asks for them to be moved or deleted. For now, we should cache
only completed blocks.
