Jim Kellerman commented on HBASE-711:
-------------------------------------
Another place we use the current time is in the creation of HLog files.
Proposal: instead of using the current time, use the current sequence number
(with leading zero padding out to some large size so the files still sort
properly). The files would still be increasing, and sort properly.
> Complain if clock skew across the cluster is badly out of sync

> Project: Hadoop HBase
> Issue Type: New Feature
> Reporter: stack
> Assignee: Jim Kellerman
> Priority: Minor
>
> 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.
