I'm using Hadoop 0.20.2 with Hive 0.11. I have succesfully inserted into
hive/hdfs some csv-files in seperate tables. selects and joins work
flawlessly. When trying to analyse some data, i needed to make use of the
built in functions of hive like:
- substr
- to_date
- rand
- etc.
for example:
select sid, request_id, to_date(times), to_unix_timestamp(times) from
contents where sid = '5000000032066010373';
sid and request id are strings here, times is a timestamp column
Unfortanetely i only get errors (always the same error stack) when using
these functions:

what am i doing wrong here? the jackson-core-asl-1.8.8.jar is in the
$HIVE_HOME/lib directory ...
SHOW FUNCTIONS;
shows me that these functions are in there ... i already tried downgrading
to hive 0.10 but the error is the same over there. i need to work with
hadoop 0.20, so unfortunately i can't try hadoop 1.x.x
thanks in advance
cheers
Wolli
