Subject [jira] Commented: (HBASE-711) Complain if clock skew across the cluster is badly out of sync
Date Wed, 06 Aug 2008 19:58:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620406#action_12620406
] 

stack commented on HBASE-711:
-----------------------------

IIUC, region A with key a start key of 10 and an end key of 12 will be named A,10,12.  When
it splits, the lower halves new name will be A,10,11 which sorts before A,10,12.  We don't
want that, right?

> hbase-710 and hbase-609 are issues where the system has broken in presence of clock skew
over the cluster.  Would be a nice service if master could flag very bad clock skew.  Regionservers
could report their local time when they ping the master.  It could do a compare.
