Andrew Purtell commented on HBASE-8326:
---------------------------------------
bq. If these Jenkins host are so overloaded as you say, a 4x slowdown vs my MBA
(which has an SSD) is entirely plausible.
In the case of EC2 Jenkins, the tests are running on a m1.xlarge backed by
instance-store ephemeral storage. It's locally attached but definitely not SSD.
> mapreduce.TestTableInputFormatScan times out frequently
