Subject [jira] [Commented] (ACCUMULO-2657) Shard randomwalk fails for 1.6.0
Date Mon, 14 Apr 2014 16:44:17 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13968510#comment-13968510
] 

Christopher Tubbs commented on ACCUMULO-2657:
---------------------------------------------

Makes sense, but whatever the Configuration says the property is, that's not the value used
by the classloader. The {{AccumuloClassLoader}} reads the accumulo-site.xml directly, and
looks for target/classes sub-directories if and only if the value is set to a non-empty value
in the accumulo-site.xml file. The apparent value exposed in the Configuration object is never
used.

As discussed in IRC, we should change this to future-proof it, so if the AccumuloClassLoader
ever did actually use the Configuration, it will not be subject to unexpected behavior. At
the very least, the test needs to be fixed so it doesn't fail because of a configuration mismatch.
