I managed to configure Phoenix 4.5 on Cloudera CDH 5.4 by recompiling the source code. sqlline.py works well, but there are problems with spark.

spark-submit --class my.JobRunner \
--master yarn --deploy-mode client \
--jars `ls -dm /myapp/lib/* | tr -d ' \r\n'` \
/myapp/mainjar.jar

The /myapp/lib folders contains the phoenix core lib, which contains class org.apache.phoenix.mapreduce.PhoenixOutputFormat. But it seems that the driver/executor cannot see it.

Exception in thread "main" java.lang.RuntimeException: java.lang.ClassNotFoundException: Class org.apache.phoenix.mapreduce.PhoenixOutputFormat not found

What can I do to overcome this exception?

  • How are you building mainjar.jar exactly? – Gillespie Sep 01 '15 at 14:58

    You're in a much better position to answer this than anyone on Stack Overflow. Check your parameters: what ends up in `--jar`? Check the jars: do they contain this class? Use `rdd.foreach` to print the classpath on the executors. Does it contain the jar? This problem needs debugging, a bounty cannot help you. – Daniel Darabos Sep 02 '15 at 08:53

Adding phoenix-core to classpath.txt solves the problem. This file is usually located under /etc/spark/conf folder.
