Glenn Weidner commented on SYSTEMML-541:
----------------------------------------
The
testReblockGroupedAggregate(org.apache.sysml.test.integration.functions.recompile.ReblockRecompileTest)
appears to fail consistently similar to original description when using seed
value of 296304710250949L. For example, the test failed when run under Eclipse
and outside via mvn command line after replacing line 102 of
ReblockRecompileTest.runReblockTest:
//long seed = System.nanoTime();
long seed = 296304710250949L;
Example of seed returned from System.nanoTime that allowed test to run
successfully:
long seed = 92558998986232L;
Note this was done using local Windows development environment.
