Summary: Support multiple storages in DataNodeCluster /
SimulatedFSDataset
Key: HDFS-12818
URL: https://issues.apache.org/jira/browse/HDFS-12818
Project: Hadoop HDFS
Issue Type: Improvement
Components: datanode, test
Reporter: Erik Krogen
Assignee: Erik Krogen
Priority: Minor
Currently {{SimulatedFSDataset}} (and thus, {{DataNodeCluster}} with
{{-simulated}}) only supports a single storage per {{DataNode}}. Given that the
number of storages can have important implications on the performance of block
report processing, it would be useful for these classes to support a multiple
storage configuration.
