Olga Natkovich commented on PIG-17:
-----------------------------------

HADOOP-1621.  FileStatus is now a concrete class and FileSystem.listPaths is deprecated and
replaced with listStatus. (Chris Douglas via omalley)

We use this in a a few places and need to move to listStatus:

ucdev3:~/src/pig/src/org/apache/pig> grep -r listPaths *
PigServer.java:    public String[] listPaths(String dir) throws IOException {
PigServer.java:        Path paths[] = pigContext.getDfs().listPaths(new Path(dir));
impl/io/.svn/text-base/FileLocalizer.java.svn-base:             paths = fs.listPaths(path);
impl/io/FileLocalizer.java:             paths = fs.listPaths(path);
impl/mapreduceExec/.svn/text-base/PigInputFormat.java.svn-base:                 Path children[]
= fs.listPaths(fullPath);
impl/mapreduceExec/PigInputFormat.java:                 Path children[] = fs.listPaths(fullPath);
impl/mapreduceExec/PigInputFormat15.java.sav:                   Path children[] = fs.listPaths(fullPath);
tools/grunt/.svn/text-base/GruntParser.jj.svn-base:                     Path paths[] = mDfs.listPaths(dfsPath);
tools/grunt/.svn/text-base/GruntParser.jj.svn-base:             Path paths[] = mDfs.listPaths(dir);
tools/grunt/GruntParser.jj:                     Path paths[] = mDfs.listPaths(dfsPath);
tools/grunt/GruntParser.jj:             Path paths[] = mDfs.listPaths(dir);
tools/grunt/GruntParser.java:                        Path paths[] = mDfs.listPaths(dfsPath);
tools/grunt/GruntParser.java:                Path paths[] = mDfs.listPaths(dir);
