Steve Loughran commented on HADOOP-8179:
----------------------------------------
Sorry, I should have given more detail.
yes, that's what it's complaining about, and yes, moving it up would be the
other solution.
If done rigorously a test ought to go with the patch too, but it is a very
small change...

> Key: HADOOP-8179
> URL: https://issues.apache.org/jira/browse/HADOOP-8179
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.24.0
> Reporter: Steve Loughran
> Priority: Minor
>
> My IDE is warning me that the {{is.close()}} method will NPE if the {{is =
> src.fs.open(src.path);}} call raises an exception, which could happen if the
> source path could not be opened. There should be an if (is!=null) wrapper
