Minibatch Preprocessing: fix dependent var with special character
JIRA:MADLIB-1237
Previously, minibatch processing would error out when the specified
dependent variable has special characters within its values. We
fixed this in two places:
1. in the query with WHERE condition, we use $$ to queto string instead
of ' ' to do string equals.
2. in the query with creating an array column, instead of using
SELECT '{ele'with*special_char, 'M,M', 'M$M'}'::text[], we call
SELECT string_to_array(''ele'with*special_char', 'M"M', 'M$M'',
',')::text[]
Install check test cases also get updated.
