Eric Badger commented on HDFS-10921:
------------------------------------
bq. Can we just change the calls to cluster.restartNameNodes() to
cluster.restartNameNode(true)?
[~xkrogen], that sounds like a reasonable change. The only reservation I have
with that is that I've encountered problems when tests use @BeforeClass to
start up a cluster and use it for all tests. If one of the tests fails and
kills the cluster, then all subsequent tests will fail because they depended on
the cluster being left in a usable state. I've seen 20 tests fail in a class
because a single test failed. Maybe that's an acceptable tradeoff for decreased
runtime, but it makes debugging the specific failure harder.
