Subject [jira] [Commented] (HBASE-9390) coprocessors observers are not called during a recovery with the new log replay algorithm
Date Thu, 05 Sep 2013 17:50:52 GMT

Andrew Purtell commented on HBASE-9390:
---------------------------------------

{noformat}
-  public boolean preWALRestore(HRegionInfo info, HLogKey logKey, WALEdit logEdit) throws
IOException
+  public void preWALRestore(HRegionInfo info, HLogKey logKey, WALEdit logEdit) throws IOException
{noformat}
we should not allow external clients to control if to recover edits. Otherwise, HBase data
integrity is nondeterministic
