Wildcard in Hadoop's FileSystem listing API calls

Question

tl;dr: To be able to use wildcards (globs) in the listed paths, one simply has to use globStatus(...) instead of listStatus(...).

---

Answer 1

Instead of listStatus you can try hadoops globStatus. Hadoop provides two FileSystem method for processing globs:

public FileStatus[] globStatus(Path pathPattern) throws IOException
public FileStatus[] globStatus(Path pathPattern, PathFilter filter) throws IOException

An optional PathFilter can be specified to restrict the matches further.
