Description

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

    <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>

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.
