Sean Busbey commented on ACCUMULO-1797:
---------------------------------------
bq. My only concern is the "The cluster may have any number of worker nodes; it
can even be a single node in psuedo-distributed mode" addition. Like Keith
already said, I'd also like to see a recommendation about running multiple
tservers or separate VMs when only a single physical host is available when
running CI/RW tests. Running tests on a single host is acceptable (and better
than nothing), but even two tservers on a single box improves the quality of
the testing.
I agree that this would be nice. I'd actually like to see a requirement that
*someone* test on a cluster of size >= 5 worker nodes (see my previous comment
above).
However, the current patch just makes explicit the current assumed requirements
around testing; that is, there is no requirement on test cluster size. Running
multiple tservers on a single host is non-trivial, because our default
configuration files and shell scripts are not conducive to it.
How about I update that paragraph to say
bq. The following tests require a Hadoop cluster running a minimum of HDFS,
MapReduce, and ZooKeeper. The cluster MAY have any number of worker nodes; it
can even be a single node in psuedo-distributed mode. A cluster with multiple
tablet servers SHOULD be used so that more of the code base will be exercised.
For the purposes of release testing, you should note the number of nodes and
versions used. See the Releasing section for more details.

> if we're going to label Hadoop platforms as supported, we should ensure the
