Spark SQL Date cache exception - apache-spark-sql

Question

I've opened spark-sql console and
create the table
create table test1(date1 date, value int)
row format delimited fields terminated by ','
stored as textfile ;
load data in the table
load data local inpath 'test1.csv' into table test1;
with the information
2015-01-01,10
2015-01-01,15
2015-01-02,10
I can execute select year(date1),month(date1),day(date1) from test
but if I run cache table test1;
I get this exception:

It looks like a bug in Spark Cache implementation for dates.
