Subject [jira] Commented: (HBASE-1483) HLog split loses track of edits
Date Thu, 04 Jun 2009 22:57:07 GMT

Clint Morgan commented on HBASE-1483:
-------------------------------------

Just tried to update 0.19 branch and don't see this change.

But I don't think that above patch fixes it. We need to to a new for each iteration of the
while(in.next(key,val)) loop...

> The same val and key references are used in the iterator, so they keep changing their
contents as we .next() through the loop.
> Thus, when we are done, all the HLogEntries in logEntries will have the same HLogEdits
and HLogKeys! I don't think this would have ever worked unless there is only one region in
the log being split.
