Zoltan Haindrich updated HIVE-17651:
------------------------------------
Description:
https://github.com/apache/hive/blob/3bfcfdde0c0be2aab1afdf5b1bc71fdcc9e77360/ql/src/java/org/apache/hadoop/hive/ql/exec/TableScanOperator.java#L259-L273
was:
It seems to me that there might be some overhead when the operator is gathering
the stats;
also check: it seems that in case vectorization is on ; the collected rowcount
would be invalid
> TableScanOperator might miss vectorization on flag
