Mike Percy commented on KUDU-1486:
----------------------------------
[~danburkert] yep, it's just ITBLL:
https://github.com/apache/incubator-kudu/blob/master/java/kudu-client-tools/src/main/java/org/kududb/mapreduce/tools/IntegrationTestBigLinkedList.java
It's currently running, if you want to investigate I can give you access to the
machine and the core file.
