Hi,
I can see that two new counters have been added for hive
(RECORDS_IN/RECORDS_OUT) in hive 0.14.
Prior to this release which counters could be used to get the records read by
hive job and records written. Because i noticed that in hive 0.14 for a few
hive jobs i see map_input_records
Hi Robin,
thanks a lot for the hint about the WITH statement. This is comparable to using
a subselect.
E.g., I could rewrite my query from:
SELECT
actor,
COLLECT_LIST(action) AS actions
FROM
foobar
GROUP BY
actor
SORT BY
actor, ts;
to:
SELECT
actor,
Probably has to do with the fact that it is an Avro table. I don't have any
experience using Avro, but maybe take a look at
https://issues.apache.org/jira/browse/HIVE-7446 for some of the issues
described there, or maybe look at the test that was added for that Jira.

Unless you can pinpoint the problem to something Tez specific, hive-specific
questions might be better off being asked on user@hive initially as there is a
larger group there that understands Hive as compared to the Tez community.
FWIW, TezTask error 1 means “something in the Hive layer using

Hi all,
I'm reading the source code of Hive cbo (CalcaitePlanner), but I find it hard
to follow.
Listed below are some of the questions:
1. What's the relationship between HepPlanner and HiveVolcanoPlanner?
2. I don't have a clue about these concepts: clusters, traitDef and
collectGarbage().
Any help?
