             Summary: Allow for configuring max_samples in range partitioner.
                 Key: SPARK-7313
                 URL: https://issues.apache.org/jira/browse/SPARK-7313
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Mridul Muralidharan
            Assignee: Mridul Muralidharan
            Priority: Minor


Currently, we assume that 1e6 is a reasonable upper bound to number of keys while sampling. This works fine when size of keys is 'small' - but breaks for anything non-trivial.
