Kihwal Lee created HDFS-4867:
--------------------------------
Summary: metaSave NPEs when there are invalid blocks in repl queue.
Key: HDFS-4867
URL: https://issues.apache.org/jira/browse/HDFS-4867
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.0.4-alpha, 0.23.7
Reporter: Kihwal Lee
Since metaSave cannot get the inode holding a orphaned/invalid block, it NPEs
and stops generating further report. Normally ReplicationMonitor removes them
quickly, but if the queue is huge, it takes very long time. Also in safe mode,
they stay.
