    <description>&lt;P&gt;&lt;A rel="user" href="https://community.cloudera.com/users/44349/davidrobison.html" nodeid="44349"&gt;@David Robison&lt;/A&gt;&lt;/P&gt;&lt;P&gt;What is the value for the following HDFS  property "dfs.client.retry.policy.enabled" ?&lt;/P&gt;&lt;PRE&gt;# su - hdfs
# hdfs getconf -confKey dfs.client.retry.policy.enabled
&lt;/PRE&gt;&lt;P&gt;.&lt;/P&gt;&lt;P&gt;DFSClient should ignore &lt;STRONG&gt;dfs.client.retry.policy.enabled&lt;/STRONG&gt; for HA proxies to ensure fast failover. Otherwise, dfsclient retries the NN which is no longer active and delays the failover.&lt;/P&gt;</description>
