------------------------------------------
> Review necessity of AggregationDesc#setGenericUDAFWritableEvaluator for bloom
> filter aggregations
> -------------------------------------------------------------------------------------------------
>
> Key: HIVE-24018
> URL: https://issues.apache.org/jira/browse/HIVE-24018
> Project: Hive
> Issue Type: Improvement
> Reporter: Stamatis Zampetakis
> Assignee: Stamatis Zampetakis
> Priority: Minor
>
> Few places in the code have following pattern
> {code:java}
> GenericUDAFBloomFilterEvaluator bloomFilterEval = new
> GenericUDAFBloomFilterEvaluator();
> ...
> AggregationDesc bloom = new AggregationDesc("bloom_filter", bloomFilterEval,
> p, false, mode);
> bloom.setGenericUDAFWritableEvaluator(bloomFilterEval);
> {code}
> where the bloom filter evaluator is passed in the constructor of the
> aggregation and directly after using a setter. The use of the setter is
> necessary otherwise there are runtime failures of the query however the
> pattern is a bit confusing.
> Investigate if there is a way to avoid the double passing of the evaluator.
> To reproduce the failure remove the setter and run the following test.
> {noformat}
> mvn test -Dtest=TestMiniLlapLocalCliDriver
> -Dqfile=vectorized_dynamic_semijoin_reduction.q -Dtest.output.overwrite
> {noformat}
