--------------------------------
Summary: Set dfs.client.retry.policy.enabled property to true when
HDFS HA is enabled
Key: AMBARI-12138
URL: https://issues.apache.org/jira/browse/AMBARI-12138
Project: Ambari
Issue Type: Improvement
Components: ambari-web
Affects Versions: 2.1.0
Reporter: sam liu
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.
