Tsz Wo Nicholas Sze commented on HDFS-9513:
-------------------------------------------
Thanks for reporting the problem and working on it.
For commitBlockSynchronization and getAdditionalDatanode, NN has storageIDs
stored in BlockUnderConstructionFeature. So we should be able to get
storageIDs from there.
For updatePipeline, NN has storageIDs stored in BlockUnderConstructionFeature
except the newly added storageID. We may choose a random storageID or the
first storageID for this case.
> 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: 邓飞
> Assignee: 邓飞
> Priority: Blocker
> Attachments: patch.HDFS-9513.20151207

> 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.
