Need to clarify globbing on command line vs in load statement
-------------------------------------------------------------
Key: PIG-2054
URL: https://issues.apache.org/jira/browse/PIG-2054
Project: Pig
Issue Type: Improvement
Components: documentation
Reporter: Olga Natkovich
Assignee: Corinne Chandel
Fix For: 0.9.0
We had several user reports saying that "globbing in Pig and Hadoop are not the
same". They based this assertion on the fact that some patterns work from
hadoop command line but would not work in Pig load statement.
Pig uses Hadoop globbing so the functionality is identical; however, when you
run on command line, shell can be doing some of the substitution giving
impression that things are different.
Example:
hadoop fs -ls
/mydata/20110423{00,01,02,03,04,05,06,07,08,09,{10..23}}00/*/part* - this works
LOAD '/mydata/20110423{00,01,02,03,04,05,06,07,08,09,{10..23}}00/*/part*' -
this does not
We should add a note to the description of globbing
