Can you send the new output of describe extended?

Subject: Re: Trouble Loading Into External Table
I got it! The combination I got to work was the following:
CREATE EXTERNAL TABLE basic
(actor_id INT, actee_id INT, properties MAP<STRING, STRING>)
ROW FORMAT DELIMITED
COLLECTION ITEMS TERMINATED BY '44'
MAP KEYS TERMINATED BY '58'
STORED AS TEXTFILE
LOCATION '/data/sample2';
This forced a DynamicSerde/TCTLSeperatedProtocol combo which didn't
work properly when I specified the field delimiter but works fine
when you only specify the other two for some reason and leave the
field delimiter as the default, I should probably file it in JIRA.
