      ndb
       - 5.5 checks that the total length of the partitioning key does not exceed MAX_KEY_LENGTH (which is 3072), for 
        varchar columns the length is 2 bytes additionally. This means that the test case which creates a table with two
        varchar(1536) columns violates this rule. 2*(1536+2) =- 3076.
      - reduce the length to 1532 for the second column. in the testcase.
       - Also fix the output of EXPLAIN in same testcase which has different "rows" count. It changed from 6 to 4.
