-------------------------------
Summary: RPC Client detect address changed should reconnect
immediately
Key: HDFS-11153
URL: https://issues.apache.org/jira/browse/HDFS-11153
Project: Hadoop HDFS
Issue Type: Bug
Components: ipc
Affects Versions: 3.0.0-alpha1
Reporter: DENG FEI
HA mode,the _*"ipc.client.connect.max.retries.on.timeouts"*_ and
_*"ipc.client.connect.max.retries"*_ is set zero,but if met active NN's ip
changed,it will detect the address is changed,but won't reconnect because
exceed the max retry times,after do 15 times failover and then throw connection
or standby exception.
maybe if found the address is changed,should reconnect immediately no matter
the retry times limit.
