Subject [jira] [Commented] (HBASE-6942) Endpoint implementation for bulk delete rows
Date Thu, 11 Oct 2012 17:05:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6942?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13474321#comment-13474321

Lars Hofhansl commented on HBASE-6942:

HRegionServer.put(..., List<Put>) does this to determine the number of successful operations:
      OperationStatus codes[] = region.batchMutate(putsWithLocks);
      for (i = 0; i < codes.length; i++) {
        if (codes[i].getOperationStatusCode() != OperationStatusCode.SUCCESS) {
          return i;
Should add this here as well. Otherwise v2 looks good.
