Subject Re: phoenix on non-apache hbase

Yes a stock client should work with a server modified for CDH assuming both client and server
versions are within the bounds specified by the backwards compatibility policy (

"Phoenix maintains backward compatibility across at least two minor releases to allow for
no downtime through server-side rolling restarts upon upgrading."

our test cluster. One of our developers wants to try out the Phoenix Spark plugin. Did you
try it out in yours too? Does it work if you did?

I could get it to build, but I couldn’t get it to work using the Phoenix installation instructions.
For some reason, dropping the server jar into CDH 5.7.0 HBase lib directory didn’t change
things. HBase seemed not to use it. Now that this is out, I’ll give it another try hoping
that there is a way. If anyone has any leads to help, please let me know.
