------------------------------------------
Summary: fix inconsistent synchronization of CachingStrategy
Key: HDFS-5676
URL: https://issues.apache.org/jira/browse/HDFS-5676
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs-client
Affects Versions: 2.4.0
Reporter: Colin Patrick McCabe
Assignee: Colin Patrick McCabe
Priority: Minor
Currently, the synchronization for {{CachingStrategy}} is a little
inconsistent. DFSOutputStream#setDropBehind modifies the strategy object, but
there's nothing protecting that object against concurrent use in
{{createBlockOutputStream}}. Similarly, {{DFSInputStream#setDropBehind}} is
synchronized, but not all the uses of {{cachingStrategy}} are.
