----------------------------------
Summary: 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: Andrew Wang
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.
