However we could only do that check if a no-arg constructor exists. > Unable to check if balancer can load > ------------------------------------ > > Key: ACCUMULO-4068 > URL: https://issues.apache.org/jira/browse/ACCUMULO-4068 > Project: Accumulo > Issue Type: Bug > Affects Versions: 1.6.4, 1.7.0 > Reporter: Keith Turner > > I was trying to use instanceOperations().testClassLoad() to check if a the RegExGroupBalancer was available. This class was added in 1.7, so I did not want to attempt to configure it in 1.6. > Unexpectedly the call to testClassLoad() failed in 1.7. I looked into the cause and it turns out the implementation of testClassLoad() also tries to instantiate the class after loading using a noarg constructor. Because of ACCUMULO-4047 the RegexGroupBalancer does not have a noarg constructor. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
