      Description

      I created an accumulo cluster using https://github.com/medined/Accumulo_1_5_0_By_Vagrant on VirtualBox. Then created a client program using https://github.com/medined/user_and_friends. This simple program threw an exception:

      Exception in thread "main" org.apache.accumulo.core.client.MutationsRejectedException: # constraint violations : 1 security codes: [] # server errors 0 # exceptions 0
      at org.apache.accumulo.core.client.impl.TabletServerBatchWriter.checkForFailures(TabletServerBatchWriter.java:536)
      at org.apache.accumulo.core.client.impl.TabletServerBatchWriter.close(TabletServerBatchWriter.java:353)

      at com.affy.UserAndFriendsDriver.main(UserAndFriendsDriver.java:67)

      On the server side, I see this exception in the Accumulo monitor:

      Failed to load constraints 2 java.lang.ClassNotFoundException: org.apache.accumulo.core.constraints.DefaultKeySizeConstraint
      java.lang.ClassNotFoundException: org.apache.accumulo.core.constraints.DefaultKeySizeConstraint

      at java.util.TimerThread.mainLoop(Timer.java:534)

      When I delete the log message, it reappears even though I do not re-run the client program.

      I don't see any reference to DefaultKeySizeConstraint in the Accumulo 1.5.0 source code that I have.

      Any ideas why this exception is thrown?
