Phoenix 5.1 doesn't actually exist yet, at least not at the Apache level. We haven't released it yet. It's possible that a vendor or user has cut an unofficial release off one of our development branches, but that's not something we can give support on. You should contact your vendor. 

Also, since I see you're upgrading from Phoenix 4.14 to 5.1: The 4.x branch of Phoenix is for HBase 1.x systems, and the 5.x branch is for HBase 2.x systems. If you're upgrading from a 4.x to a 5.x, make sure that you also upgrade your HBase. If you're still on HBase 1.x, we recently released Phoenix 4.15, which does have a supported upgrade path from 4.14 (and a very similar set of features to what 5.1 will eventually get).

Hello All,

We are trying to upgrade the phoenix version from "apache-phoenix-4.14.0-cdh5.14.2" to "APACHE_PHOENIX-5.1.0-cdh6.1.0."

I couldn't find out any upgrade steps for the same. Please help me out to get any documents available. 
I have downloaded the below phoenix parcel and trying to access some DML operation. I am getting the following error
