Benoit Perroud commented on HADOOP-7344:
----------------------------------------
I fall into this issue, and my (ugly) workaround is the following :
Create a public class in the package {{org.apache.hadoop.fs}} to be able to
access the package restricted class {{GlobExpander}}
{noformat}
package org.apache.hadoop.fs;
public class PublicGlobExpander extends GlobExpander {
}
{noformat}
And have a {{FileSystemHelper}} class that contains at least the following
function (basically expanding the path and calling {{FS.globStatus}} on every
components found) :
{noformat}
public static FileStatus[] globStatus(FileSystem fs, final Path
pathPattern) throws IOException {
final String filename = pathPattern.toUri().getPath();
final List<String> filePatterns = PublicGlobExpander.expand(filename);
final List<FileStatus> statuses = new LinkedList<FileStatus>();
for (final String filePattern : filePatterns) {
final FileStatus[] tmpStatuses = fs.globStatus(new
Path(filePattern));
if (tmpStatuses == null) {
continue;
}
for (final FileStatus status : tmpStatuses) {
statuses.add(status);
}
}
return statuses.toArray(new FileStatus[statuses.size()]);
}
{noformat}
Really looking forward to see the a {{if (files == null) continue;}} at line
1277 !
> 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
>
> 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.
