Siddharth Seth commented on HIVE-14052:
---------------------------------------
An AppId needs to be created (required for a bunch of processing). We also need
a hive queryId, which is a string. The appId was being used as this unique
identifier. However, it wasn't being used everywhere, which resulted in
multiple log files. The patch moves the AppId creation further up, and uses it
in the config so that a single log file is created.
Same as a regular query - 2 appIds. One for the query, one for LLAP itself.
> Cleanup of structures required when LLAP access from external clients
> completes

> Per [~sseth]: There's no cleanup at the moment, and structures used in LLAP
> to track a query will keep building up slowly over time.
