[jira] Commented: (HADOOP-3064) Exception with file globbing
closures
[ https://issues.apache.org/jira/browse/HADOOP-3064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581118#action_12581118 ]
Hairong Kuang commented on HADOOP-3064:
---------------------------------------
This is a problem whenever a file name contains a comma. I am thinking to escape commas before saving the input paths to a jobconf and unescape it after reading it from the jobconf.

> Reporter: Tom White

> Using file globbing to select various input paths, like so:
> conf.setInputPath(new Path("mr/input/glob/2008/02/{02,08}"));
> gives an exception:
> Exception in thread "main" java.io.IOException: Illegal file pattern:
> Expecting set closure character or end of range, or } for glob {02 at
> 3

> The code for JobConf.getInputPaths tokenizes using
