我正在使用CDH 5.8。 当我打开火花壳 并发出以下命令：
sqlContext.tableNames
res0: Array[String] = Array()
我没有获得已经创建的配置单元表。 它应该给我这个：
res0: Arragy[String] = Array(clickstream)
可能出现什么问题？
hive shell表现正常
hive> show tables;
OK
clickstream

这是spark-shell的日志
[cloudera@quickstart ~]$ spark-shell

我可以清楚地看到这可能是问题所在：
17/04/01 12:33:56 WARN metastore.ObjectStore: Version information not found in metastore. hive.metastore.schema.verification is not enabled so recording the schema version 1.1.0

但是这个决议是什么？ 我也重启了VM（Ctrl + Alt + Del）。
