Subject [jira] [Created] (HADOOP-13710) Supress CachingGetSpaceUsed from logging interrupted exception stacktrace
Date Tue, 11 Oct 2016 19:45:20 GMT
Wei-Chiu Chuang created HADOOP-13710:
----------------------------------------

             Summary: Supress CachingGetSpaceUsed from logging interrupted exception stacktrace
                 Key: HADOOP-13710
                 URL: https://issues.apache.org/jira/browse/HADOOP-13710
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 2.8.0
            Reporter: Wei-Chiu Chuang
            Priority: Minor


CachingGetSpaceUsed thread is typically interrupted when the node is shutdown. Since this
is a routine operation, there seems not much value to print the stacktrace of an {{InterruptedException}}.
