David Medinets created ACCUMULO-1877:
----------------------------------------
Summary: ClassNotFoundException: DefaultKeySizeConstraint
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

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

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?
