Subject [jira] Updated: (HBASE-1718) Reuse of KeyValue during log replay could cause the wrong data to be used
Date Tue, 28 Jul 2009 23:51:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1718?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Gray updated HBASE-1718:
---------------------------------

    Attachment: HBASE-1718-v1.patch

Instantiates a new KeyValue at the end of the while loop, meaning we only re-instantiate once
we've passed forward the KV (we can reuse the times we do continue).

> Our meta table got a row key of METAROW in it.  Hard to explain how it happened, but
under code inspection stack found that we are reusing the same KV instance for each replayed
key.
