Karan Mehta commented on PHOENIX-3942:
--------------------------------------
[~jamestaylor]
HBase 1.1 didn't have {{ServerSideScanMetrics}} class which contains the
metrics {{ROWS_SCANNED}} and {{ROWS_FILTERED}}. It was introduced in 1.2. This
is the reason for NPE when accessing those metrics from the {{ScanMetrics}} map
returned by the server.
The fix would be as follows
{code}
- static final String COUNT_OF_ROWS_FILTERED_KEY_METRIC_NAME =
"ROWS_FILTERED";
- static final String GLOBAL_BYTES_IN_RESULTS_METRIC_NAME =
"BYTES_IN_RESULTS";
-
scanMetricsHolder.getCountOfRowsScanned().change(scanMetricsMap.get(COUNT_OF_ROWS_SCANNED_KEY_METRIC_NAME));
-
scanMetricsHolder.getCountOfRowsFiltered().change(scanMetricsMap.get(COUNT_OF_ROWS_FILTERED_KEY_METRIC_NAME));
{code}
Will submit a patch soon for this branch.
