Re: Correct way of using regexserde
Yes it is to create an external table that points your data with the regexp passed with the SERDE. good day 2013/7/2 Mohammad Tariq donta...@gmail.com Hello there, Thanks a lot for the response. Do you mean creating an external table?I have also tried deleting ouputregex, but same result. And the jar is also added.

I have verified my regex through http://www.regexplanet.com/advanced/java/index.html and it's working fine there. But when i'm using the same pattern with regexserde i'm getting NULL. My input looks like this : SOME_CHARACTER_STRING and I want to extract the characters enclosed between the angle brackets. This is the command i'm using : hive CREATE TABLE s(f1 STRING) ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe' WITH SERDEPROPERTIES ( input.regex = (\\w*), output.regex = %1$s) STORED AS TEXTFILE; LOAD works fine, but SELECT * gives me NULL. I am on hadoop-1.0.4 and hive-0.10.0 Thank you so much for you time. Warm Regards, Tariq cloudfront.blogspot.com
