------------------------------------
Summary: DistributedHBaseCluster should not restore the cluster if
CM is not used
Key: HBASE-9703
URL: https://issues.apache.org/jira/browse/HBASE-9703
Project: HBase
Issue Type: Bug
Reporter: Enis Soztutar
Assignee: Enis Soztutar
Fix For: 0.98.0, 0.96.1
At the end of integration tests, we are calling
DistributedCluster.restoreCluster() in case CM has killed nodes so that we can
leave the cluster in the same state that we have taken over.
However, if CM is not used in a test (for example ITLoadAndVerify), but some
regions servers die, or an external daemon kills the servers, we will still
try to restore at the end of the test which may or may not succeed (depending
on configuration, the region server going being unaccessible, etc. )
We can do two things, either do a best effort restore cluster which will not
fail the test if there are any errors, or we can skip running restore if no
disruptive actions have taken place.
I am leaning towards the former one, since if an RS goes down with or w/o CM
due to bad disk etc., we cannot restore the cluster, but we should not fail the
test in this case.
