> globStatus doesn't grok groupings with a slash
> ----------------------------------------------
>
> Key: HADOOP-7344
> URL: https://issues.apache.org/jira/browse/HADOOP-7344
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 0.23.0
> Reporter: Daryn Sharp
> Assignee: Colin Patrick McCabe
> Fix For: 2.3.0
>
>
> If a glob contains a grouping with a single item that contains a slash, ex.
> "{a/b}", then globStatus throws {{"Illegal file pattern: Unclosed group near
> index 2"}} -- regardless of whether the path exists. However, if the glob
> set contains more than one item, ex. "{a/b,c}", then it throws a
> {{NullPointerException}} from {{FileSystem.java:1277}}.
> {code}
> 1276: FileStatus[] files = globStatusInternal(new Path(filePattern), filter);
> 1277: for (FileStatus file : files) {
> 1278: results.add(file);
> 1279: }
> {code}
> The method {{globStatusInternal}} can return null, so the iterator fails with
> the NPE.
