Subject [jira] [Commented] (ACCUMULO-1169) Can't build against CDH3U5
Date Tue, 12 Mar 2013 03:39:12 GMT


Hudson commented on ACCUMULO-1169:

Integrated in Accumulo-1.5-Hadoop-2.0 #27 (See [])
    ACCUMULO-1169 A much easier solution to differing "throws" declarations is to just not
be specific about the Exception being thrown. (Revision 1455385)

     Result = UNSTABLE

>             Fix For: 1.5.0
> 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.
