Hive on spark 执行加载不了spark的jars

问题展示

Launching Job 1 out of 1
In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=
In order to limit the maximum number of reducers:
  set hive.exec.reducers.max=
In order to set a constant number of reducers:
  set mapreduce.job.reduces=
Failed to execute spark task, with exception 'org.apache.hadoop.hive.ql.metadata.HiveException(Failed to create Spark client for Spark session 8ffa76f2-907e-4092-987d-6c89279f3c5b)'
FAILED: Execution Error, return code 30041 from org.apache.hadoop.hive.ql.exec.spark.SparkTask. Failed to create Spark client for Spark session 8ffa76f2-907e-4092-987d-6c89279f3c5b

最后用一下命令查找日志：

hive --hiveconf hive.root.logger=DEBUG,console

找到报错原因：

截图如下

最后分析是因为hive加载不了spark的jars

hive-env.sh 添加

export SPARK_HOME=/opt/module/spark-2.4.5-bin-without-hive
export SPARK_JARS=""
for jar in `ls $SPARK_HOME/jars`; do
    export SPARK_JARS=$SPARK_JARS:$SPARK_HOME/jars/$jar
done
export HIVE_AUX_JARS_PATH=/opt/module/hadoop-3.1.3/share/hadoop/common/hadoop-lzo-0.4.21-SNAPSHOT.jar$SPARK_JARS
