Ok, glad to hear you got it working.
I don't do any work with the CDH-based releases. Pedro is the primary
maintainer of these -- I imagine he's watching this email list. Does the
4.14.0-cdh5.11.2 release not contain a phoenix-spark2 jar? Maybe the
explanation is just that the spark2 integration wasn't backported into
that release... not sure.

sorry for bad copy-paste, versions we have combined together are
phoenix-4.14.0-cdh5.11.2-client.jar and
phoenix-spark2-4.7.0.2.6.5.3002-10.jar (from last release
4.7.0.2.6.5.3002-10 (17.8.2018)) -worked for us.

Hello, thank you for your response. It gave me a tip :)
I've reviewd one more time our JAR's.
Before we used
* phoenix-4.14.0-cdh5.11.2-client.jar
* phoenix-spark-4.14.0-cdh5.11.2.jar
Becouse they came together with APACHE_PHOENIX
4.14.0-cdh5.11.2.p0.3*Cloudera parcel* from
http://www.apache.org/dist/phoenix/apache-phoenix-4.14.0-cdh5.11.2/parcels/
The only available version for our environment .
But now I've found Phoenix-Spark2
https://javalibs.com/artifact/org.apache.phoenix/phoenix-spark2
I've installed/configured this one and it works.
One thing - last Release 4.14.0-cdh5.11.2 (9.6.2018) , which has
Spark2 JAR phoenix-spark2-4.7.0.2.6.5.3002-10.jar -
We got really confused with it, because of release number 4.7,
which looks like old Phoenix version and because this is for
Hortonworks.
In any way *phoenix-4.14.0-cdh5.11.2-client.jar* and
*phoenix-4.14.0-cdh5.11.2-client.jar* are working for us, at least
we can load and save data from/to Phoenix.

Lots of details missing here about how you're trying to submit
these
Spark jobs, but let me try to explain how things work now:
Phoenix provides spark(1) and spark2 jars. These JARs provide the
implementation for Spark *on top* of what the
phoenix-client.jar. You
want to include both the phoenix-client and relevant
phoenix-spark jars
when you submit your application.
This should be how things are meant to work with Phoenix 4.13
and 4.14.
If this doesn't help you, please give us some more specifics
about the
commands you run and the output you get. Thanks!
