[jira] [Created] (HDFS-16610) Make fsck read timeout configurable

Stephen O'Donnell created HDFS-16610:

             Summary: Make fsck read timeout configurable
                 Key: HDFS-16610
                 URL: https://issues.apache.org/jira/browse/HDFS-16610
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
            Reporter: Stephen O'Donnell
            Assignee: Stephen O'Donnell


In a cluster with a lot of small files, we encountered a case where fsck was very slow. I believe it is due to contention with many other threads reading / writing data on the cluster.

Sometimes fsck does not report any progress for more than 60 seconds and the client times out. Currently the connect and read timeout are hardcoded to 60 seconds. This change is to make them configurable.
