Hi,
The sandbox 2.2 comes with hive 0.14. Does it also have the bug? If so,
how can I patch hive on sandbox?

Hi
This has been fixed recently https://issues.apache.org/jira/browse/HIVE-9529.
Merging is triggered in two different ways. INSERT/CTAS can trigger merging of
small files and CONCATENATE can trigger merging of small files. The later had a
bug which generated MR task instead of TEZ task which was fixed recently.
Earlier one will use TEZ task always.
Thanks

Hi,
Is there anyone using hortonworks sandbox 2.2? I am trying to use hive on Tez
on the sandbox. I set the running engine in hive-site.xml to Tez.
<property>
<name>hive.execution.engine</name>
<value>tez</value>
</property>
Then I ran the script that alters a table to merge small orc files (alter table
orc_merge5a partition(st=0.8) concatenate;). The merging feature worked, but
Hive does not use Tez, it used MapReduce, so weird!
Another point, I tried to run the same script on the production cluster which
is on always Tez, the merging feature sometimes worked, sometimes did not.
I would appreciate any suggestions.
