stack commented on HBASE-1627:
------------------------------
Thanks for persisting. Its I who is think. Yes, will retry once only since we
redo the next inside the catch block. Let me commit. Good stuff.
> TableInputFormatBase#nextKeyValue catches the wrong exception
> -------------------------------------------------------------
>
> Key: HBASE-1627
> URL: https://issues.apache.org/jira/browse/HBASE-1627
> Project: Hadoop HBase
> Issue Type: Bug
> Affects Versions: 0.20.0
> Reporter: Doğacan Güney
> Priority: Minor
> Attachments: tableinput.patch
>
>
> TableInputFormatBase#nextKeyValue only catches UnknownScannerException from
> Scanner.next. However, scanner may throw other exceptions:
> {code}
> /* from HTable.ClientScanner#next */
> try {
> values = getConnection().getRegionServerWithRetries(callable);
> } catch (IOException e) {
> if (e instanceof UnknownScannerException &&
> lastNext + scannerTimeout < System.currentTimeMillis()) {
> ScannerTimeoutException ex = new ScannerTimeoutException();
> ex.initCause(e);
> throw ex;
> }
> throw e;
> }
> {code}
> Is there any reason why TIFB does not catch ScannerTimeoutException?
