[jira] Created: (HBASE-2448) Scanner threads are interrupted without acquiring lock properly

Scanner threads are interrupted without acquiring lock properly
---------------------------------------------------------------

                 Key: HBASE-2448
                 URL: https://issues.apache.org/jira/browse/HBASE-2448
             Project: Hadoop HBase
          Issue Type: Bug
          Components: master
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical


There are a few places where scanner threads are interrupted with .interrupt() instead of .interruptIfAlive(). This means that if they're in the midst of the checkFileSystem operation, it'll end up catching the interruption there, determine that the filesystem is down, and shut down the whole server. Other nasties can also result.
