Hive / HCatalog Forum

Using HIVE Corr gives erroneous results

    HI
    I am trying to correlate some temperatures and power consumption.
    When I use HIVE Corr on a small number of values in the Sandbox I get the correct result.
    When I use PIG COR which is slow, I get also the right results.When I use HIVE CORR, which is fast the results are complete wrong on a scale of up to a factor of 10. Both values are double. Does any body have similar experiences? Could CORR be incorrectly implemented on HDInsight?

The forum ‘Hive / HCatalog’ is closed to new topics and replies.
