-----------------------------------
Summary: NN periodically unlinks lazy persist files with missing
replicas from namespace
Key: HDFS-6929
URL: https://issues.apache.org/jira/browse/HDFS-6929
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
Fix For: HDFS-6581
Occasional data loss is expected when using the lazy persist flag due to node
restarts. The NN will optionally unlink lazy persist files from the namespace
to avoid them from showing up as corrupt files.
This behavior can be turned off with a global option. In the future this may be
made a per-file option controllable by the client.
