Stamatis Zampetakis updated HIVE-25919:
---------------------------------------
Description:
The following queries fail with a {{ClassCastException}} when the optimizer
tries to push the predicates in the underlying HBase table.
{code:sql}
CREATE TABLE hbase_table(row_key string, c1 boolean, c2 boolean)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES (
"hbase.columns.mapping" = ":key,cf:c1,cf:c2"
);
-- Q1
select * from hbase_table where c1 and c2;
-- Q2
select * from hbase_table where c1=true and c2=true;
{code}
{code:java}
ClassCastException org.apache.hadoop.hive.ql.plan.ExprNodeColumnDesc cannot be
cast to org.apache.hadoop.hive.ql.plan.ExprNodeGenericFuncDesc

The failure in Q2 is probably related to HIVE-13815 since the expression (c1 =
true and c2 = true) is simplified to (c1 and c2) leading to the exception above
but the problem was probably there even before as Q1 is failing as well with
the same stacktrace.
