ketan kunde commented on SPARK-9858:
------------------------------------

[~aroberts] : did this exchangecordinator suite test cases pass for your big endian environment, exclusively test cases by the following name

 

test(s"determining the number of reducers: complex query 1

test(s"determining the number of reducers: complex query 2 

The above test cases are also seen failing on my big endian environment with the below respective logs
 * determining the number of reducers: complex query 1 *** FAILED ***
 Set(1, 2) did not equal Set(2, 3) (ExchangeCoordinatorSuite.scala:424)
- determining the number of reducers: complex query 2 *** FAILED ***
 Set(4, 2) did not equal Set(5, 3) (ExchangeCoordinatorSuite.scala:476)

Since this ticket is RESOLVED i would like to know from you what is the change u did to ensure passing of this test cases

Also could you also highlight which exact feature of spark does this test case test

I would be very greatful for your reply.

 

Regards

Ketan
