stack resolved HBASE-2258. -------------------------- Resolution: Fixed Hadoop Flags: [Reviewed] Committed on branch and trunk. > The WhileMatchFilter doesn't delegate the call to filterRow() > ------------------------------------------------------------- > > Key: HBASE-2258 > URL: https://issues.apache.org/jira/browse/HBASE-2258 > Project: Hadoop HBase > Issue Type: Bug > Components: filters > Affects Versions: 0.20.3 > Reporter: Dan Washusen > Fix For: 0.20.4 > > Attachments: HBASE-2258.patch > > > While testing the recent MemStoreScanner slowness I noticed that each scan in > the randomSeekScan test takes about 19 seconds to complete. The scan in > question provides a startRow and a WhileMatchFilter containing a PageFilter > that asks for 120 rows. I would have expected this scan to return in roughly > the same amount of time as a scan that specifies a startRow and stopRow that > spans a similar number of rows. > As it turns out this is an issue with the WhileMatchFilter. The > WhileMatchFilter is not delegating the call the filterRow() down the the > PageFilter. As a result the PageFilter never increments the rowsAccepted > counter. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
