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!

Hello !
I wonder if there any way how to get working Phoenix 4.13 or 4.14 with
Spark 2.1.0
In production we used Spark SQL dataframe to load from and write data to
Hbase with Apache Phoenix (Spark 1.6 and Phoenix 4.7) and it worked well.
After upgrade , we faced an issues with loading and writing, it is not
possible anymore.
Our environment:
·Cloudera 5.11.2,
·HBase 1.2
·Spark 2.1.0(parcel , compatible with Coudera 5.11.2)
·APACHE_PHOENIX 4.14.0-cdh5.11.2.p0.3 (we tested 4.13 as well)
We read/write data by Python (Pyspark library) but the same errors will
come also writing in Scala.
*Read data from Phoenix 4.13 with Spark 2.1.0 error :*
Py4JJavaError:An error occurred while calling o213.load.
: java.lang.NoClassDefFoundError: org/apache/spark/sql/DataFrame
*Read data from Phoenix 4.14 with Spark 2.1.0 error :*
Py4JJavaError:An error occurred while calling o89.load. :
com.google.common.util.concurrent.ExecutionError:
java.lang.NoSuchMethodError:

(Disruptor .jar versions changing - did not solve the issue)
*Insert data to Phoenix 4.14 with Spark 2.1.0 error:*
Py4JJavaError:An error occurred while calling o186.save.
:java.lang.AbstractMethodError:
org.apache.phoenix.spark.DefaultSource.createRelation(Lorg/apache/spark/sql/SQLContext;Lorg/apache/spark/sql/SaveMode;Lscala/collection/immutable/Map;Lorg/apache/spark/sql/Dataset;)Lorg/apache/spark/sql/sources/BaseRelation;
Actually we areawarethat Spark2 failed to read and write Phoenix due to
Spark changing the DataFrame API, as well as a Scala version change, the
resultant JAR isn't binary compatible with Spark versions < 2.0.
*DataFrame class is missing from Spark 2 and *This issues was fixed ONCE
by patch for Phoenix versioon
4.10https://issues.apache.org/jira/browse/PHOENIX-3333
Unfortanatly this patch is not sutable for our enviroment, Could you
please comment whether other versions of Phoenix has such fix?
How to read/write data from Phoenix 4.13/or 4.14 using Spark2?
