[jira] [Created] (ACCUMULO-3937) Hard-coded HDFS failure tolerance

Josh Elser created ACCUMULO-3937:
------------------------------------

             Summary: Hard-coded HDFS failure tolerance
                 Key: ACCUMULO-3937
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3937
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.7.0
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Blocker
             Fix For: 1.7.1, 1.8.0


ACCUMULO-2480 added an error cache to the TabletServer which makes the tserver kill itself after 5 errors creating a new WAL file within 10 seconds.

This is painful because it now causes Accumulo to kill itself if HDFS is restarted beneath Accumulo. Previously, I would have expected Accumulo to just keep on chugging if HDFS goes away. Now, I'll have to restart it when HDFS returns.

This should be a configuration property instead of being hard-coded.
