One of the items which is important for emerging, more flexible hadoop deployments is multitenancy.
JIRA's such as this one: https://issues.apache.org/jira/browse/MAPREDUCE-5571
Are very hard to test, and it would be extremely useful to many people deploying non standard hadoop environments , if they could test that multitenant and multiuser support was functional on their cluster.
This is sort of related to the stress tests jira https://issues.apache.org/jira/browse/BIGTOP-1065, also recently created.
I'm not really even sure this is possible in a fully automated / iTest sort of fashion... so to start, any thoughts on how bigtop should test multi user, multi tenant workloads? One simple way to do it would be to launch 4 or 5 "calculate pi" jobs at one time, maybe from different users? But how could we "predict" off hand the usernames which will be available and appropriate to submit jobs on a cluster, without the user specifying them?
In any case, bigtop smokes is ideal for this kind of testing, because this kind of testing is really only applicable to a cluster which is being used by for a real deployment. Other tests (i.e. pig smoke tests) are well handled and covered by the individual ecosystem projects.
