Spark is not connected to Hive correctly.

[dukechain2333]

I have already create a new database in Hive, however, when I excute the following code in spark-shell, it seems that spark goes to the wrong metastore_db as shown in this this page Spark Documentation

scala> spark.sql("show databases").show()
+---------------+
|databaseName|
+---------------+
| default      |
+---------------+

hive> show databases;
OK
default
