[jira] Updated: (HADOOP-3498) File globbing alternation should be
able to span path components
[ https://issues.apache.org/jira/browse/HADOOP-3498?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robert Chansler updated HADOOP-3498:
------------------------------------
Release Note: Extended file globbing alternation to cross path components. For example, {/a/b,/c/d} expands to a path that matches the files /a/b and /c/d. (was: File globbing alternation can now cross path components. For example, {/a/b,/c/d} expands to a patch that matches the files /a/b and /c/d.)

> 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.
