我在我的spark配置中添加了一个包（在spark-default.conf中），但是当我使用livy创建一个新会话时，它会导致我出现问题（请参阅下面的错误）以及 session 和 death 。ps：当我删除这个包时一切正常。

我使用：cloudera hdp2.6.5：
- 火花2.3
- 活生生的 0.7.0
- Hadoop 2.7
- lib 无监督（https://github.com/unsupervise/spark-tss）
步 ：
- livy conf => livy.spark.master 纱线集群
- spark-default conf => spark.jars.repositories https://dl.bintray.com/unsupervise/maven/
- spark-defaultconf => spark.jars.packages com.github.unsupervise:spark-tss:0.1.1
