我正在尝试在REPL上创建一个spark会话（在Linux x86_64上）并且我得到以下错误。
你能告诉我吗？
>echo $PATH
/opt/installations/spark-2.2.0-bin-hadoop2.7/bin:/opt/local/installations/scala-2.11.8/bin:/opt/env/java/latest/bin:/opt/env/java/latest/jre/bin:/opt/env/oracle/latest/bin:/opt/env/oracle/latest/network/admin:/opt/jre/1.6.0_81l64/bin:/bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin:/usr/local/sbin:.
能够运行直到我使用getOrCreate函数
