[jira] [Created] (IMPALA-11047) Preconditions.checkNotNull(statsTuple_) fail in HdfsScanNode.java if PARQUET_READ_STATISTICS=0

Riza Suminto created IMPALA-11047:
-------------------------------------

             Summary: Preconditions.checkNotNull(statsTuple_) fail in HdfsScanNode.java if PARQUET_READ_STATISTICS=0
                 Key: IMPALA-11047
                 URL: https://issues.apache.org/jira/browse/IMPALA-11047
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Impala 4.0.0
            Reporter: Riza Suminto


There is a conflict happening in HdfsScanNode.java vs RuntimeFilterGenerator.java when initializing overlap predicate.

In HdfsScanNode.java, computeStatsTupleAndConjuncts that init statsTuple_ will not be called because PARQUET_READ_STATISTICS=0.
[https://github.com/apache/impala/blob/9d61bc4/fe/src/main/java/org/apache/impala/planner/HdfsScanNode.java#L409]

 

On the other hand, in RuntimeFilterGenerator.java, disable_overlap_filter is set to false without considering what is the value of PARQUET_READ_STATISTICS.
