Lefty Leverenz commented on HIVE-16724:
---------------------------------------
Doc note: This adds *hive.llap.zk.sm.session.timeout* to HiveConf.java, so it
needs to be documented for release 2.4.0.
* [Configuration Properties -- LLAP |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAP]
Added a TODOC2.4 label.

> ZKDTSM in Hadoop uses 10sec by default; looking at some logs from a flaky ZK
> instance, I see that most other clients have 40-90sec. timeouts.
> ZKDTSM uses sharedvalue from curator; that instantly fails on session
> expiration, without any retries. For now we are going to increase the session
> timeout to minimize problems due to that.
