--------------------------------------
[~hyukjin.kwon], the failure is releated with the performance of arm instance,
now we donate an arm instance to AMPLab and we havn't build the python job yet,
and we plan to donate some higher performance arm instances to AMPLab next
month, if the issues happen again then I will create a pr to fix this. Thanks a
lot.
