Subject [jira] [Commented] (HIVE-17968) TPCDS query70 generates NPE in vectorization, works fine with vectorization disabled.
Date Tue, 07 Nov 2017 15:16:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16242162#comment-16242162

Matt McCline commented on HIVE-17968:
-------------------------------------

[~ndembla] New writeSingleRow on master doesn't use getWritableKeyValue anymore.  I wonder
what version of master you are using.  Thanks

{noformat}  private void writeSingleRow(VectorHashKeyWrapper kw, VectorAggregationBufferRow
agg)
      throws HiveException {

    int colNum = 0;
    final int batchIndex = outputBatch.size;

    // Output keys and aggregates into the output batch.
    for (int i = 0; i < outputKeyLength; ++i) {
      keyWrappersBatch.assignRowColumn(outputBatch, batchIndex, colNum++, kw);
    }
    for (int i = 0; i < aggregators.length; ++i) {
      aggregators[i].assignRowColumn(outputBatch, batchIndex, colNum++,
          agg.getAggregationBuffer(i));
    }
    ++outputBatch.size;
    if (outputBatch.size == VectorizedRowBatch.DEFAULT_SIZE) {
      flushOutput();
    }
  }
