> ScanMetrics counter update may not happen in case of exception in
> TableRecordReaderImpl.nextKeyValue(),
> There are multiple cases as below,

> 2. While creating a new scanner,
> {code}
> if (lastSuccessfulRow == null) {

> long now = System.currentTimeMillis();
> LOG.info("Mapper took " + (now-timestamp)

> LOG.info(ioe.toString(), ioe);
> String lastRow = lastSuccessfulRow == null ?
