Release Note

The patch introduces a new command line parameter for pig: -useHCatalog which imports the appropriate jars for pig use with HCatalog. This reduces the burden of finding all the relevant jars for using HCatalog with pig. If the user has setup the home directories for hive/hcatalog those would be used else defaults (/usr/lib/hive...) are assumed.

Description

Currently to use hcat from pig (via HCatLoader/HCatStorer) user need to register bunch of jars and set couple of configuration. For a novice user, it is non-trivial to find all the relevant jars and config params. We should have better integration between Pig & HCat by pre-configuring Pig to load all these jars and configs.
