Subject [jira] Commented: (HBASE-711) Complain if clock skew across the cluster is badly out of sync
Date Tue, 05 Aug 2008 23:00:44 GMT

    [ https://issues.apache.org/jira/browse/HBASE-711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12620080#action_12620080
] 

Jim Kellerman commented on HBASE-711:
-------------------------------------

Noting the clock skew won't work because HRegionInfo constructor uses clock time to set the
region name.

However, do we really need to disambiguate region names with the clock time?
Since region name = table name + start key + end key, can it ever be the case that you would
have two regions with the same name?

> 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.
