Well, I must say sorry that there was a mistake in the last email.
The maximum number of the valid keys is 32 in my test. Namely, key33~key50 get
null values in the code.
Still waiting for more details, thanks!

Dear all,
by doing some tests, I found there is a limit to the number of fields used
in GRPOUPING SETS.
For example, in the code below, we can only get null value for key44~key50.
In addition, if we change the order of the keys, we can always get null
value for the last several keys.
I am pleased to announce the release of MR3 0.5.
A new feature of MR3 0.5 is its native support for Kubernetes. Now the user
can run Hive on Kubernetes by using MR3 as its execution engine. The
documentation on Hive on Kubernetes can be found at:
