Some simple features in Hive can really bring down the learning curve
for new users. I am teaching some how to use hive.
A buddy if mine did this.
hive> select * from mt_date_test;
a 2010-01-01 NULL
b 2009-12-31 NULL
c 2010-01-27 NULL
hive> select * from mt_date_test where my_date > '2010-01-01';
2010-01-27 08:18:27,008 map = 100%, reduce =100%
Ended Job = job_200909171715_20264
I instantly suspected 1) whiteplace 2) delimeters
hive> select key from mt_date_test;
Should we use a pipe | or some other column delimiter like the mysql
CLI does? and have this be a property that is on by default
In its current state the user understandably made the assumption that
'>' does not work on strings.
Should we add some expose the format of the results in Driver so that
the CLI can effectively split the rows by column?
