Jing Zhao created HDFS-4052:
-------------------------------
Summary: FSNameSystem#invalidateWorkForOneNode and
FSNameSystem#computeReplicationWorkForBlock in branch-1 should print debug
information outside of the namesystem lock
Key: HDFS-4052
URL: https://issues.apache.org/jira/browse/HDFS-4052
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 1.2.0, 3.0.0
Reporter: Jing Zhao
Assignee: Jing Zhao
Priority: Minor
Currently in branch-1, both FSNameSystem#invalidateWorkForOneNode and
FSNameSystem#computeReplicationWorkForBlock print debug information (which can
be a long msg generated by traversing a list/array) without releasing the
FSNameSystem lock. It would be better to move them outside of the namesystem
lock.
This may also apply to FSNameSystem#invalidateWorkForOneNode in trunk.
