Spark does not show up in Hue

Hi,

I have recently installed the latest Cloudera 5.3.2 using Parcels on a cluster. Everything looks good except Spark, which does not appear in the "Query Editors" menu(see the screenshot). The Spark shell works, but not in Hue, which is important for us. I have tried the standalone version of Spark and YARN-based. The same result. I do not see anything suspicious in Hue or Spark logs.

If I try to re-compile it, I get

File "/opt/cloudera/parcels/CDH-5.3.2-1.cdh5.3.2.p0.10/lib/hue/build/env/lib/python2.7/site-packages/Django-1.4.5-py2.7.egg/django/db/backends/sqlite3/base.py", line 288, in _cursor
self._sqlite_create_connection()

self.connection = Database.connect(**kwargs)

although I have configured Hue to use MySQL instead of SQLite to store its metadata. Any ideas?

Best regards,
Sergey
