Riju Trivedi commented on HIVE-27113:
-------------------------------------

Thrift message size can go beyond 1g for wide tables with too many partitions 
(5k+), Hence increasing the default to max value 2 GB.

> Increasing default for hive.thrift.client.max.message.size to 2 GB

> Documentation on the help suggests setting 2147483648 while Integer Max is 
> 2147483647. So, it actually becomes -1 and gets set to thrift default limit
