Junping Du updated HDFS-3498: ----------------------------- Summary: Make Replica Removal Policy pluggable and ReplicaPlacementPolicyDefault extensible for reusing code in subclass (was: Make ReplicaPlacementPolicyDefault extensible for reuse code in subclass) > Make Replica Removal Policy pluggable and ReplicaPlacementPolicyDefault > extensible for reusing code in subclass > --------------------------------------------------------------------------------------------------------------- > > Key: HDFS-3498 > URL: https://issues.apache.org/jira/browse/HDFS-3498 > Project: Hadoop HDFS > Issue Type: Bug > Components: data-node > Affects Versions: 1.0.0, 2.0.0-alpha > Reporter: Junping Du > Assignee: Junping Du > Attachments: HDFS-3498-v2.patch, HDFS-3498-v3.patch, > HDFS-3498-v4.patch, HDFS-3498.patch, > Hadoop-8471-BlockPlacementDefault-extensible.patch > > > ReplicaPlacementPolicy is already a pluggable component in Hadoop. However, > the Replica Removal Policy is still nested in BlockManager that need to be > separated out into a ReplicaPlacementPolicy then can be override later. Also > it looks like hadoop unit test lack the testing on replica removal policy, so > we add it here. > On the other hand, as a implementation of ReplicaPlacementPolicy, > ReplicaPlacementDefault still show lots of generic for other topology cases > like: virtualization, and we want to make code in > ReplicaPlacementPolicyDefault can be reused as much as possible so a few of > its methods were changed from private to protected. -- This message is automatically generated by JIRA.
