Description

For example,

{/a/b,/c/d} should expand to /a/b and /c/d. This change would also permit a consistent syntax for specifying multiple input paths to MapReduce, streaming and Pig by specification of a single glob path with alternation {/a/b,/c/d}

, rather than a collection of comma separated glob paths /a/b,/c/d.

This change would also make globbing more consistent with bash, which supports this feature.
