Lefty Leverenz commented on HIVE-16082:
---------------------------------------
Doc note: This adds *hive.llap.task.communicator.listener.thread-count* to
HiveConf.java, so it needs to be documented in the LLAP section of
Configuration Properties.
* [Configuration Properties -- LLAP |
https://cwiki.apache.org/confluence/display/Hive/Configuration+Properties#ConfigurationProperties-LLAP]
Added a TODOC2.2 label.
> Allow user to change number of listener thread in LlapTaskCommunicator

> Now LlapTaskCommunicator always has same number of RPC listener thread with
> TezTaskCommunicatorImpl. There are scenarios when we want them different: for
> example, in Llap only mode, we want less TezTaskCommunicatorImpl's listener
> thread to reduce off-heap memory usage.
