[jira] Updated: (HBASE-2075) HBaseMaster requires HDFS superuser
privileges due to waitOnSafeMode
[ https://issues.apache.org/jira/browse/HBASE-2075?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bassam Tabbara updated HBASE-2075:
----------------------------------
Description:
Repro:
1) Enable dfs.permissions
2) Start HBaseMaster in a different linux user account from HDFS.
I get the following exception in the log. It looks like waitOnSafeMode requires HDFS superuser privileges which I do not grant to HBase.
