[PIG-1566] Support globbing for registering jars in pig script.

• Type: Improvement
• Status: Closed
• Priority: Major
• Resolution: Fixed
• Affects Version/s: 0.7.0
• Fix Version/s: 0.9.0
• Hadoop Flags: Reviewed

Release Note

User can use globbing in register statement. Pig will search for matching jars in local file system (either relative path or absolute path). eg:

register /homes/user/pig/*.jar
register *.jar
register jars/*.jar

Relative path is relative to user's working directory.

Globbing does not support remote file system such as hdfs, s3 (register without globbing do).

The behavior for register without globbing remains the same.

Description

Currently user can not register pig jars with globing.

For example following register script will fail.

register /etc/jars/*.jar

It will be great if we can support such globing for registering jars.

Release notes:
We allow globbing in register statement. User can use "*" to denote a globbing, eg:
register key*.jar
register /home/jarpath/key*.jar
register jars/key*.jar

The path can be absolute path or relative path start with working directory.

Note globbing does not further search in classpath as non-globbing case does, eg:
"register key1234.jar" works if key1234.jar in classpath, but not in working directory, however,
"register key*.jar" will not locate key1234.jar in this case.
