Andrew Kyle Purtell resolved HBASE-6277. ---------------------------------------- Resolution: Invalid > Metrics for scan object are overwritten when restart() is called > ---------------------------------------------------------------- > > Key: HBASE-6277 > URL: https://issues.apache.org/jira/browse/HBASE-6277 > Project: HBase > Issue Type: Bug > Reporter: Ted Yu > Priority: Major > > From HBASE-4145: > There's an issue in {{TableRecordReaderImpl}}. Calling restart() does this: > {code} > public void restart(byte[] firstRow) throws IOException { > currentScan = new Scan(scan); > {code} > Which by itself is fine since the metrics will be copied from *scan* to > *currentScan*, except that it's *currentScan* that has the updated metrics > not *scan*. > In other words, *currentScan* is the object that is used for scanning so it > contains the metrics. If restart() is called, that object is overwritten by > the original definition of the {{Scan}}. I think to fix this we could grab > the metrics from *currentScan* first then set them back on the new object. -- This message was sent by Atlassian Jira (v8.20.7#820007)
