Subject [jira] [Updated] (HBASE-8462) Custom timestamps should not be allowed to be negative
Date Tue, 30 Apr 2013 01:58:16 GMT

     [ https://issues.apache.org/jira/browse/HBASE-8462?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enis Soztutar updated HBASE-8462:
---------------------------------

    Attachment: hbase-8462_v1.patch

Attaching a patch, which basically throws IllegalArgumentException from Scan, Put, and Delete.
Note that KeyValue should still allow negative timestamps, otherwise a cluster containing
negative timestamps will not be able to operate. 

Please review carefully.

> Client supplied timestamps should not be allowed to be negative, otherwise unpredictable
results will follow. Especially, since we are encoding the ts using Bytes.Bytes(long), negative
timestamps are sorted after positive ones. Plus, the new PB messages define ts' as uint64.
