Subject [jira] [Created] (ACCUMULO-1169) Can't build against CDH3U5

------------------------------------

             Summary: Can't build against CDH3U5
                 Key: ACCUMULO-1169
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1169
             Project: Accumulo
          Issue Type: Improvement
          Components: tserver
    Affects Versions: 1.5.0
         Environment: branch 1.5
            Reporter: Josh Elser
            Assignee: Keith Turner
            Priority: Critical


I tried to compile 1.5 against CDH3U5 recently and noticed that I could no longer do so due
to a change in server/o.a.a.s.m.r.HadoopLogCloser.

In CDH3U5, DistributedFileSystem#recoverLease(Path) throws IOException *and* NoSuchMethodException,
whereas 0.20.205, 1.0.4, 1.1.0, and 2.0.3-ALPHA (I believe that was the list I checked; regardless,
a large majority of Apache Hadoop releases).

I believe we could do some reflection magic here to catch when the underlying DistributedFileSystem
throws the additional exception, and thus know when we have to catch it.

It would be nice to have this in for 1.5 to support customers who want to use CDH3, but I
can understand objections to putting work-arounds in for non-Apache Hadoop versions.

I'll also try to get a patch together today for this if no one beats me to it.
