Description

When I'm running systemml, with data set about 1000 instances, 30000 features(actually only 15 not zero feature per instance), the task always failed with output below :

[Stage 28:> (0 + 12) / 12]17/09/08 10:21:33 WARN scheduler.TaskSetManager: Lost task 2.0 in stage 28.0 (TID 225, sd002021.skydata.com, executor 6): java.lang.ArrayIndexOutOfBoundsException: 0
