> I do insert overwrite select on a partitioned table. Partition column is
> specified dynamically from select query. "ceil" function is applied on a
> string column to specify partition for each row. Reduce sink gets confused
> about the type of partition column. It leads to following cast exception in
> runtime:
> {code:java}
> Caused by: java.lang.ClassCastException:
> org.apache.hadoop.hive.ql.exec.vector.LongColumnVector cannot be cast to
> org.apache.hadoop.hive.ql.exec.vector.BytesColumnVector

> The problem is reproducible by running mvn test
> -Dtest=TestMiniLlapLocalCliDriver -Dqfile=insert0.q with "set
> hive.stats.autogather=false". The additional config option causes insert
> statements to be vectorized so the vectorization bug appears.
