--------------------------------

             Summary: Investigate lock issue in o.a.h.hdfs.shortcircuit.DfsClientShmManager.EndpointShmManager
                 Key: HDFS-8961
                 URL: https://issues.apache.org/jira/browse/HDFS-8961
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Mingliang Liu


There are two clauses in {{hadoop-hdfs}} to filter out the findbugs warnings in {{org.apache.hadoop.hdfs.shortcircuit.DfsClientShmManager$EndpointShmManager}}:

{code}
    <Match>
      <Class name="org.apache.hadoop.hdfs.shortcircuit.DfsClientShmManager$EndpointShmManager"
/>
      <Method name="allocSlot" />
      <Bug pattern="UL_UNRELEASED_LOCK_EXCEPTION_PATH" />
    </Match>
    <Match>
      <Class name="org.apache.hadoop.hdfs.shortcircuit.DfsClientShmManager$EndpointShmManager"
/>
      <Method name="allocSlot" />
      <Bug pattern="UL_UNRELEASED_LOCK" />
    </Match>
{code}

These two warnings show up in the Jenkins run as these classes are moved into the {{hadoop-hdfs-client}}
module. We either need to fix the code or move these clauses to the {{hadoop-hdfs-client}}
module.
