Subject [jira] [Commented] (HBASE-6562) Fake KVs are sometimes passed to filters
Date Thu, 03 Jan 2013 19:52:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6562?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13543229#comment-13543229

Ted Yu commented on HBASE-6562:
-------------------------------

I ran the following two tests which use either createLastOnRowCol() or createLastOnRow():

  356  mt -Dtest=TestDataBlockEncoders
  357  mt -Dtest=TestHalfStoreFileReader

They passed.

> In internal tests at Salesforce we found that fake row keys sometimes are passed to filters
(Filter.filterRowKey(...) specifically).
> The KVs are eventually filtered by the StoreScanner/ScanQueryMatcher, but the row key
is passed to filterRowKey in RegionScannImpl *before* that happens.
