UNION ALL is supported on Tez 0.4 onwards. If any of the tables are empty,
that could be an issue- refer HIVE-8227
Thanks

Hey Anusha,
You sure about that?
The following works for me:
set hive.execution.engine=tez;
Trying to run a query on Tez with the following configurations
*set hive.tez.container.size=5120*

Hi,
Needed info on where I can get detailed job counters for Hive on Tez. Am
running this on a HDP cluster with Hive 0.13 and see only the following job
counters through Hive Tez in Yarn logs . Cannot see any ReduceOperator
counters and the CPU_MILLISECONDS in some cases in -ve. Is this accurate?
Am using 0.13.0 version of hive with parquet table having 34 columns
with the following props while creating the table
*CLUSTERED BY (udid) SORTED BY (udid ASC) INTO 256 BUCKETS
STORED as PARQUET
TBLPROPERTIES (parquet.compression=SNAPPY); *
The query I am running is
*set

Hi ,
I tried the same with compute statistics for columns a, b,c as above and
still seeing the same results in explain plan.
How do I confirm if its generating all the column stats for a given column.
If this is confirmed, we can debug why Hive is still not using it?
Thanks

I am trying to enable Column statistics usage with Parquet tables. This is
the query I am executing. However on explain, I see that even though *Basic
stats: COMPLETE *is seen *Column stats *is seen as* NONE.*
Can someone please explain what else I need to debug/fix this.

Hi,
I do not see any examples of extending ORC with bloom filters on Hive
documentation. Can someone please explain what exactly needs to be done to
enable this.
Thanks
