Having some databases and tables in them in Hive instance. I'd like to show tables for some specific database (let's say 3_db).

+------------------+--+
|  database_name   |
+------------------+--+
| 1_db             |
| 2_db             |
| 3_db             |
+------------------+--+

If I enter beeline from bash-nothing complex there, I just do the following:

show databases;
show tables from 3_db;

When I'm using pyspark via ipython notebeook- my cheap tricks are not working there and give me error on the second line (show tables from 3_db) instead:

sqlContext.sql('show databases').show()
sqlContext.sql('show tables from 3_db').show()

What seems to be wrong and why's the same code works in one place and don't work in another?

sqlContext.sql("show tables in 3_db").show()
