Subject [jira] Created: (HBASE-2161) get rid of scanner timeout
Date Fri, 22 Jan 2010 21:22:21 GMT
get rid of scanner timeout

                 Key: HBASE-2161
                 URL: https://issues.apache.org/jira/browse/HBASE-2161
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: ryan rawson
             Fix For: 0.21.0

the client side code has this in ClientScanner.next():

            if (e instanceof UnknownScannerException &&
                lastNext + scannerTimeout < System.currentTimeMillis()) {
              ScannerTimeoutException ex = new ScannerTimeoutException();
              throw ex;

This will cause the client-side to timeout after the 'scannerTimeout'. There doesn't seem
to be any good reason for this - we can just restart the scanner at the last row.  Leave the
server-side scanner as is, but clients should be able to have a 5 day scan that is continuously
being restarted.
