I am using Ubuntu 14.04 and have installed Derby 10.12.1.1. I have followed installation instructions from Apache website.

My CLASSPATH has been set as

/usr/local/hadoop/lib/*:/usr/local/hive/lib/*:/usr/local/derby/lib/derbynet.jar:/usr/local/derby/lib/derbytools.jar

When I try to start Derby 

hduser@HadoopMaster:/usr/local/derby/data$ /usr/local/derby/bin/startNetworkServer

I get 

Tue Nov 10 23:50:18 AEDT 2015 : Security manager installed using the Basic server security policy.

    Check your CLASSPATH very carefully. Sealing violations often arise when you accidentally have multiple different versions of the Derby software at different locations within your CLASSPATH. – Bryan Pendleton Nov 10 '15 at 22:50

    Thanks so much Bryan. You are absolutely correct. The hive/lib also contains an older derby.jar that must have been causing the issue. – Maz Nov 15 '15 at 04:53
  • Which derby.jar should be removed Or What to do ? – Ashutosh Shukla Oct 30 '16 at 13:03

    Sorry @ashu17188 for not replying earlier. Have been a bit inactive. If I remember correctly then the lib folder inside hive installation had a couple derby jars which I had to remove. I have recently installed Hive 2 and associated Derby. Did not have any issues this time. – Maz Feb 05 '17 at 08:53
