------------------------------------
Summary: HAadmin transtionToActive with forceActive option can
show confusing message.
Key: HDFS-7059
URL: https://issues.apache.org/jira/browse/HDFS-7059
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.0.0-alpha, 3.0.0
Reporter: Rushabh S Shah
Assignee: Rushabh S Shah
Ran into this confusing message on our local HA setup.
One of the namenode was down and the other was in standby mode.
The namenode was not able to come out of safe mode so we did transitionToActive
with forceActive switch enabled.
Due to change in HDFS-2949, it will try connecting to all the namenode to
see whether they are active or not.
But since the other namenode is down it will try connect to that namenode for
'ipc.client.connect.max.retries' number of times.
Every time it is not able to connect, it will log a message :
INFO ipc.Client: Retrying connect to server: <server name>. Already tried 0
time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=50,
sleepTime=1000 MILLISECONDS)
Since in our configuration, the number of retries is 50, it will show this
message 50 times.
