Anu Engineer commented on HDFS-11469:
-------------------------------------
[~xyao] Thanks for the patch. It looks very good overall. Some very minor
comments.
* Nit: ContainerMapping.java: Line 99: typo: plugable -> pluggable
* Can we make the replication factor an enum instead of int ?
* Nit: We seem to have disabled 3 tests, file a JIRA to track them ?
* Nit: Typo in class name -- *SCMContainerPlacemenRandom*
* In the node placement SCMContainerPlacemenRandom.java:Line 66: Do we need to
make a copy of the lists, Same comment for capacity placement class.

> The initial patch will make the datanode chosen policy for container creation
> pluggable. It will add at least two built-in policies:
> 1. random (existing)
> 2. utilization of the storage on different data nodes.
> Additional policy based on
> 3. storage type, etc. will be added separately.
