> 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 running query.[error_id:
> message: "Failure while running fragment. < UnsupportedOperationException:[ Attemped
to access a DeadBuf. This would happen if you attempted to interact with a buffer that has
been moved or not yet initialized. ]"
