Ted Yu updated HBASE-7715: -------------------------- Fix Version/s: 0.96.0 Status: Patch Available (was: Open) > 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.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. -- This message is automatically generated by JIRA.
