Subject [jira] Updated: (HADOOP-1968) Wildcard input syntax (glob) should support {}
Date Fri, 05 Oct 2007 01:31:50 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-1968?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Hairong Kuang updated HADOOP-1968:

    Attachment: curlyGlob1.patch

The patch uses StringBuilder in stead of StringBuffer. I feel that the use of lex & Yacc
is a too big project now. So the new patch does not incorporate this suggestion.

> We have users who have organized data by day and would like to select several days in
a single input specification.  For example they would like to be able to say:
> '/data/2007{0830,0831,0901}/typeX/'
> To input 3 days data into map-reduce (or Pig in this case). 
> (Also the use of regexp to resolve glob paterns looks like it might introduce some other
bugs.  I'd appreciate it if someone took another look at the code to see if there are any
file characters that could
> be interpreted as regexp "instructions").
