Thejas M Nair commented on HIVE-11630:
--------------------------------------
Other possible optimizations around the multiple copies of HiveConf (separate
jiras might be better for these )-
1. Create new HiveConf objects using copy constructor (if its not already
done), to avoid parsing the xml files every time
2. Create HiveConf that supports copy-on-write semantics, as hiveconf does not
usually change that frequently.
> Use string intering with HiveConf to be more space efficient

> The giant enum HiveConf#ConfVars has a String field varname. Each new session
> on HiveServer2 creates a new conf object, which means wastefully creating the
> varname string for each enum object.
