Example 1 with ContainerRequestProto

use of org.apache.hadoop.hdds.protocol.proto.StorageContainerLocationProtocolProtos.ContainerRequestProto in project ozone by apache.

the class StorageContainerLocationProtocolClientSideTranslatorPB method allocateContainer.

 * @param factor - Replication Count
 * @param owner  - Service owner of the container.
