---------------------------------------
Summary: Skip Retry INFO logging on first failover from a proxy
Key: HADOOP-17116
URL: https://issues.apache.org/jira/browse/HADOOP-17116
Project: Hadoop Common
Issue Type: Task
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
RetryInvocationHandler logs an INFO level message on every failover except the
first. This used to be ideal before when there were only 2 proxies in the
FailoverProxyProvider. But if there are more than 2 proxies (as is possible
with 3 or more NNs in HA), then there could be more than one failover to find
the currently active proxy.
To avoid creating noise in clients logs/ console, RetryInvocationHandler should
skip logging once for each proxy.
