Subject Re: Confusion Installing Phoenix Spark Plugin / Various Errors
Date Wed, 09 Dec 2015 03:49:10 GMT
Hi Jonathan,

Spark only needs the client JAR. It contains all the other Phoenix
dependencies as well.

I'm not sure exactly what the issue you're seeing is. I just downloaded and
extracted fresh copies of Spark 1.5.2 (pre-built with user-provided
Hadoop), and the latest Phoenix 4.6.0 binary release.

I copied the 'phoenix-4.6.0-HBase-1.1-client.jar' to /tmp and created a
'spark-defaults.conf' in the 'conf' folder of the Spark install with the
following:

spark.executor.extraClassPath /tmp/phoenix-4.6.0-HBase-1.1-client.jar
spark.driver.extraClassPath /tmp/phoenix-4.6.0-HBase-1.1-client.jar

I then launched the 'spark-shell', and was able to execute:

import org.apache.phoenix.spark._

>From there, you should be able to use the methods provided by the
phoenix-spark integration within the Spark shell.

Good luck,

Josh
