[jira] [Updated] (PIG-3566) Cannot set useMatches of
REGEX_EXTRACT_ALL and REGEX_EXTRACT
[ https://issues.apache.org/jira/browse/PIG-3566?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nezih Yigitbasi updated PIG-3566:
---------------------------------
Description:
In the javadoc of REGEX_EXTRACT_ALL and REGEX_EXTRACT it says we can set the 'useMatches' property of these UDFs with DEFINE statements:
DEFINE GREEDY_EXTRACT REGEX_EXTRACT_ALL(false);
DEFINE NON_GREEDY_EXTRACT REGEX_EXTRACT(false);
However, both of these do not work (2013-11-07 15:35:15,107 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 1200: <line 7, column 40> mismatched input 'false' expecting RIGHT_PAREN)
These UDFs should take string arguments to their constructors.

Probably because the UDFs can only accept string arguments to their constructors. These UDFs should take string arguments to their constructors.
