在Phoenix 4.5的CDH 5.4上运行Spark Job时找不到PhoenixOutputFormat [英] PhoenixOutputFormat not found when running a Spark Job on CDH 5.4 with Phoenix 4.5

问题描述

我通过重新编译源代码设法在Cloudera CDH 5.4上配置了Phoenix 4.5。 sqlline.py 效果很好，但是存在火花问题。

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

/ myapp / lib 文件夹包含phoenix核心库，该库包含类 org.apache.phoenix.mapreduce.PhoenixOutputFormat 。

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.

推荐答案

在类路径中添加 phoenix-core 。 txt解决了这个问题。该文件通常位于/ etc / spark / conf文件夹下。

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