Subject [jira] [Commented] (ACCUMULO-2780) MiniDFSCluster has binary incompatible change between Hadoop 1 & 2
Date Fri, 22 May 2015 00:10:17 GMT


Christopher Tubbs commented on ACCUMULO-2780:

This issue was marked to be fixed for 1.5.3. However, no patch has been provided, and development
on 1.5 is waning. Non-urgent issues are not likely to be addressed. Users are encouraged to
upgrade to a newer version of Accumulo.

So, I've removed the fixVersion for 1.5.3. I've also removed 1.7.1, because 1.7.0 dropped
support for Hadoop 1, so this won't be an issue.

I'm also inclined to close as "Won't Fix" for 1.6 also, because it's a test class, and the
simplest solution is to simply perform a clean on the build task {{mvn clean ... }}. Thoughts?

>             Fix For: 1.6.3
> We have a test class (start/src/test/java/org/apache/accumulo/test/
that relies on MiniDFSCluster's getFileSystem method. This method had a binary incompatible
method signature change between Hadoop 1 and Hadoop 2.
> This causes successive runs of maven with different hadoop profiles activated to fail
with a method not found exception.
> The test should instead get hte URI it needs either by retrieving the dfs uri from the
MiniAccumuloCluster.getConfig call or if needed calling the MiniAccumuloCluster.getFilesystem
method rather than the MiniDFSCluster.getFilesystem method.
