Project: Apache Drill
Issue Type: Bug
Reporter: Neeraja
Trying to perform a join across Hive table and HBase table using following
queries (with and without sub-query). HBase just has one row corresponding one
of the users in Hive table.
select c_custkey from hive.customer where c_custkey in (select
cast(up.`row_key` as int) from hbase.`userprofile` up);
select c.c_custkey from hive.customer c JOIN hbase.`userprofile` up ON
c.c_custkey=cast(up.`row_key` as int) ;
The second query returns no results and the first one returns the exception
below.
Query failed: org.apache.drill.exec.rpc.RpcException: Remote failure while
