----------------------------------------
Summary: Backport DirectoryScanner improvements HDFS-14476,
HDFS-14751 and HDFS-15048 to branch 3.2 and 3.1
Key: HDFS-15583
URL: https://issues.apache.org/jira/browse/HDFS-15583
Project: Hadoop HDFS
Issue Type: Improvement
Components: datanode
Reporter: Stephen O'Donnell
Assignee: Stephen O'Donnell
HDFS-14476, HDFS-14751 and HDFS-15048 made some good improvements to the
datanode DirectoryScanner, but due to a large refactor on that class in
branch-3.3, they are not trivial to backport to earlier branches.
HDFS-14476 introduced the problem in HDFS-14751 and a findbugs warning, fixed
in HDFS-15048, so these 3 need to be backported together.
