Hello, I am using HDP 2.6 version. When I run a query on Hive tables Tez job failed, killed/failed due to:OWN_TASK_FAILURE. Error do not have much information, and cannot able to resolve this issue. Looks like similar issue has been experienced by many people, but I could not find a solution in HWX xommunity. failed for even basic queries like select max(column1) from table; select count(*) from table; insert into table(data merge) with large number of records. Please help out, Any inputs can be appriciated. Error is something like: -------------------------------------------------------------------------------- VERTICES STATUS TOTAL COMPLETED RUNNING PENDING FAILED KILLED -------------------------------------------------------------------------------- Map 1 ..........
