HBASE-15638  is where I'm trying to find the classloader magic. tl;dr I've not 
found it yet. [~Apache9]

Do we only accept Endpoints with pb2.5? I think it is really hard to support 
both pb2.5 and pb3 for Endpoint? Maybe some classloader magic?

Thanks.

One question on the pom upgrade.
When I did this some time back I found this,
Just adding the note I had stored when we did this upgrade
{code}
the actual protoc.exe version shows 3.0.0 but the protobuf-java .jars are of 
3.0.0-beta2. so things does not work. 
Since when we configure 3.0.0-beta 2 in hbase pom the protoc says it needs 
3.0.0. When we configure 3.0.0 in hbase pom
it says canoot find 3.0.0 protobuf jar. Hence renmaed 3.0.0-beta2 jar to 3.0.0 
protobuf jar.
{code}
Also how were you able to compile the .proto files under src/test folder?

Just a note to say that upgrading our pb to pb3 w/o running protoc3, we do 
pretty good but fail reading trailers on hfiles. We can't find CellComparator. 
TODO: check why.

Attached patch is pretty much same as a patch that [~ram_krish] and 
[~anoop.hbase] have been slinging around for a while only in this case, 
ByteStringer and HBaseZeroCopyByteString are removed. Posting to see what fails 
in our test run.
