-----------------------------------
Summary: Reduce KMS error logging severity from WARN to INFO
Key: HDFS-14404
URL: https://issues.apache.org/jira/browse/HDFS-14404
Project: Hadoop HDFS
Issue Type: Improvement
Components: kms
Affects Versions: 3.2.0
Reporter: Kitti Nanasi
Assignee: Kitti Nanasi
When the KMS is deployed as an HA service and a failure occurs the current
error severity in the client code appears to be WARN. It can result in
excessive errors despite the fact that another instance may succeed.
Maybe this log level can be adjusted in only the load balancing provider.
