Unable to instantiate SparkSession with Hive support because Hive classes are not found.

CDH集群执行spark sql，出现下面错误：
 
ERROR ApplicationMaster:94 - User class threw exception: java.lang.IllegalArgumentException: Unable to instantiate SparkSession with Hive support because Hive classes are not found.
java.lang.IllegalArgumentException: Unable to instantiate SparkSession with Hive support because Hive classes are not found.

一、在节点查看linux下

/opt/cloudera/parcels/CDH/lib/hive/bin  hive能否正常执行。如不正常，处理hive问题。

二、上述正常，

处理步骤：

1.查看 /opt/cloudera/parcels/CDH/lib/spark/jars 下是否有 spark-hive_2.11-2.4.0-cdh6.3.1.jar，及权限。

2.查看/opt/cloudera/parcels/CDH/lib/spark/conf 下是否有 yarn-conf 配置文件，及权限。

3.查看/etc/spark 是否配置conf 、conf.cloudera.spark_on_yarn

4. yarn-conf 下包括

core-site.xml
hadoop-env.sh
hbase-env.sh
hbase-site.xml
hdfs-site.xml
jaas.conf
mapred-site.xml
ssl-client.xml
topology.map
topology.py
yarn-site.xml

5.是否创建软连接 ：ln -s /etc/spark/conf.cloudera.spark_on_yarn  spark-conf。

6.查看 /opt/cloudera/parcels/CDH-6.3.1-1.cdh6.3.1.p0.1470567/etc/spark/conf.dist 下

是否配置
