Ming Ma updated HDFS-9015:
--------------------------
Attachment: HDFS-9015.patch
The patch refactors TestReplicationPolicy* test code in the following ways:
* Move common code to a new base class {{BaseReplicationPolicyTest}}.
* Parameterize {{TestReplicationPolicy}} and
{{TestReplicationPolicyConsiderLoad}} so that we can use the test code if they
apply to other block placement policies.
* {{TestReplicationPolicyConsiderLoad}} used to test only one default rack even
though the test set up two racks for the DNs. That is because it calls
{{dnManager.registerDatanode(dnr);}} which ends up resolving to the
"/default-rack" network location instead of using the pre-built
DatanodeDescriptors. The intention of the test case is to test the specified
topology. The test case has been fixed to accomplish that.

> TestReplicationPolicy can be parameterized so that default policy, upgrade
> domain policy and other policies can share some common test cases.
