    Description

      ToDate() function doesnt work with a partitioned table, partitioned by the column of DATE Datatype.
      Below are the steps I followed to recreate the problem.
      -->Sample input file to hive table :
      hdfs@testhost ~$ cat test.log

      grunt> temp = LOAD 'partmytable' using org.apache.hive.hcatalog.pig.HCatLoader();
      grunt> temp1 = FILTER temp by dt == ToDate('2012-06-13','yyyy-MM-dd');
      grunt> dump temp1;
      -->Try to filter the normal table with same statement works;
      grunt>
      grunt> temp = LOAD 'mytable' using org.apache.hive.hcatalog.pig.HCatLoader();
      grunt> temp1 = FILTER temp by dt == ToDate('2012-06-13','yyyy-MM-dd');
      grunt> dump temp1;
      Workaround :
      Use below statement instead of direct ToDate();
      grunt>temp1 = FILTER temp5 by DaysBetween(dt,(datetime)ToDate('2012-06-13', 'yyyy-MM-dd')) >=(long)0 AND DaysBetween(dt,(datetime)ToDate('2012-06-13', 'yyyy-MM-dd')) <=(long)0;
