> FSUtils#waitOnSafeMode can incorrectly loop on standby NN
> ---------------------------------------------------------
>
> Key: HBASE-7715
> URL: https://issues.apache.org/jira/browse/HBASE-7715
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.94.4
> Reporter: Andrew Wang
> Assignee: Ted Yu
> Fix For: 0.96.0
>
> Attachments: 7715-trunk-v2.txt, 7715-trunk-v3.txt
>
>
> We encountered an issue where HMaster failed to start with an active NN not
> in safe mode and a standby NN in safemode. The relevant lines in
> {{FSUtils.java}} show the issue:
> {noformat}
> while
> (dfs.setSafeMode(org.apache.hadoop.hdfs.protocol.FSConstants.SafeModeAction.SAFEMODE_GET))
> {
> {noformat}
> This call skips the normal client failover from the standby to active NN, so
> it will loop polling the standby NN if it unfortunately talks to the standby
> first.
