------------------------------------
Summary: Improve datanode shutdown latency
Key: HDFS-15618
URL: https://issues.apache.org/jira/browse/HDFS-15618
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode
Reporter: Ahmed Hussein
Assignee: Ahmed Hussein
The shutdown of Datanode is a very long latency. A block scanner waits for 5
minutes to join on each VolumeScanner thread.
Since the scanners are daemon threads and do not alter the block content, it is
safe to ignore such conditions on shutdown of Datanode.
