What is the value of hive.tez.log.level? My guess is this happens only in DEBUG 
log level.

Thanks

We have a UDF in hive which take in some values and outputs a score. When 
running a query on a table which calls the score function on every row, looks 
like tez is not running the query on YARN, but trying to run it in local mode. 
It then runs out of memory trying to insert that data into a table.

Here's the query

ADD JAR score.jar;
CREATE TEMPORARY FUNCTION score AS 'hive.udf.ScoreUDF';

CREATE TABLE abc AS
SELECT
    id,
    score(col1, col2) as score
    , '2016-10-11' AS dt
FROM input_table
;

Here's the output of the shell

Query ID = hadoop_20161028232841_5a06db96-ffaa-4e75-a657-c7cb46ccb3f5

It looks like the job is not getting submitted to the cluster, but running 
locally. We can't get tez to run the query on the cluster.
The hive shell starts with an Xmx of 4G.

If I set hive.execution.engine = mr, then the query works, because it runs on 
the hadoop cluster.

What should we change to avoid this problem?

Thanx
