JDBC connection to Shark Server hangs

I am using following configuration for my shark cluster

  • Scala 2.10.3
  • Spark 0.9.0
  • Hive 0.12.0-chd5.0.2
  • Shark 0.9.0

Spark and Hive are configured via Cloudera manager (CDH 5.0.2)

I am following this tutorial to connect to shark server: https://cwiki.apache.org/confluence/display/Hive/HiveClient

I start shark server as follows:./shark --service sharkserver 9956

I am able to connect to hive server using code in above mentioned tutorial. But when i try to connect to shark server it hung at this line

Connection con = DriverManager.getConnection("jdbc:hive://localhost:9956/default", "", "");

It does not give any error or exception, just program stuck at that line.

I was able to solve this problem by running server in sudo mode. In default mode shark server was unable to write a file because of permission denied error.
