DENG FEI resolved HDFS-9513.
----------------------------
Resolution: Workaround
> DataNodeManager#getDataNodeStorageInfos not backward compatibility

> Key: HDFS-9513
> URL: https://issues.apache.org/jira/browse/HDFS-9513
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client, namenode
> Affects Versions: 2.2.0, 2.7.1
> Environment: 2.2.0 HDFS Client &2.7.1 HDFS Cluster
> Reporter: DENG FEI
> Assignee: DENG FEI
> Priority: Blocker
> Attachments: HDFS-9513-20160621.patch, patch.HDFS-9513.20151207,
> patch.HDFS-9513.20151216-2.7.2

> We is upgraded our new HDFS cluster to 2.7.1,but we YARN cluster is
> 2.2.0(8000+,it's too hard to upgrade as soon as HDFS cluster).
> The compatible case happened datasteamer do pipeline recovery, the NN need
> DN's storageInfo to update pipeline, and the storageIds is pair of
> pipleline's DN,but HDFS support storage type feature from 2.3.0
> [HDFS-2832|https://issues.apache.org/jira/browse/HDFS-2832], older version
> not have storageId ,although the protobuf serialization make the protocol
> compatible,but the client will throw remote exception as
> ArrayIndexOutOfBoundsException.
