Lefty Leverenz commented on HIVE-15570:
---------------------------------------
Doc note: The new description and behavior of
*hive.llap.client.consistent.splits* need to be documented in the wiki for
release 2.2.0:
* [Configuration Properties -- hive.llap.client.consistent.splits |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-hive.llap.client.consistent.splits]
Added a TODOC2.2 label.
(By the way, the parameter description should have included newlines (\n) as
shown for *hive.llap.validate.acls* right after it, to avoid overlong lines in
the generated template file hive-default.xml.template.)

> Sometimes user might prefer to run with "hive.execution.mode=container" mode
> when LLAP is stopped. If hive config for LLAP had
> "hive.llap.client.consistent.splits=true" in client side, it would end up
