DataNode pipelining : failure on mirror make results in failure on upstream
datanode
------------------------------------------------------------------------------------
Key: HADOOP-3007
URL: https://issues.apache.org/jira/browse/HADOOP-3007
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.16.0
Reporter: Raghu Angadi
Priority: Blocker
Fix For: 0.16.2
When datanode is transfering data to other datanodes (as opposed to a client
write()), DN currently receiving the data is supposed to continued to receive
even if the downstream (mirror) datanode fails.
I think there are two minor bugs in receiveBlock() :
# mirrorSock masks this.mirrorSock, which could be set to null by other members
like receiveChunk() to indicate failure.
# when this.mirrorSock is non null, failure to write to it at in receiveBlock()
should be handled same way as in receiveChunk().
I am not sure if this should block 0.16.1, but should surely block 0.16.2.
