> Key: ACCUMULO-1877
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1877
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.5.0
> Environment: Ubuntu 12.04, Hadoop 1.2.1, Zookeeper 3.4.3
> Reporter: David Medinets
> Priority: Minor
>
> 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
> org.apache.accumulo.core.client.impl.BatchWriterImpl.close(BatchWriterImpl.java:52)
> 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

> 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?
