Suresh Srinivas created HDFS-4987: ------------------------------------- Summary: Namenode changes to track multiple storages Key: HDFS-4987 URL: https://issues.apache.org/jira/browse/HDFS-4987 Project: Hadoop HDFS Issue Type: Sub-task Components: namenode Reporter: Suresh Srinivas
Currently namenode track in BlockInfo, the corresponding DataNodeDescriptor. I propose changing this with new abstraction StorageDescriptor. This change will also make DatanodeDescriptor a collection of StroageDescriptors. This will allow given a block, identify its storage and also Datanode. -- This message is automatically generated by JIRA.
