----------------------------------
Hi Experts,
The patch is generated basing on the latest Apache Ambari official branch
origin/branch-2.1, however it's weird that it failed to be applied on the jira
system.
Any comments?
> Set dfs.client.retry.policy.enabled property to true when HDFS HA is enabled

> After enabling HDFS HA, hdfs-site.xml does not include property
> dfs.client.retry.policy.enabled and 'hdfs getconf -confKey
> dfs.client.retry.policy.enabled' returns empty value.
> The property dfs.client.retry.policy.enabled is important when HA is enabled,
> as it enables HDFS client retry in case of NameNode failure. So, after
> enabling HDFS HA, Ambari should set this property to true in hdfs-site.xml.
