Description

If you do:

create external table test_table (
id int)
partitioned by (day string)
row format serde 'org.apache.hadoop.contrib.serde2.RegexSerDe'
with serdeproperties (
'input.regex' = '.* ([^ ]*)'
);

alter table test_table add partition (day='2011-09-01');

alter table test_table set serdeproperties (
'input.regex' = '(.*)'
);

alter table test_table add partition (day='2011-09-02');

The first partition will still use the older regex and the new one will use the new regex. It would be great if the change in serdeproperties was applied to existing partitions too.
