Colin Patrick McCabe updated HDFS-5766:
---------------------------------------
Summary: In DFSInputStream, do not add datanode to deadNodes after
InvalidEncryptionKeyException in fetchBlockByteRange (was: bypass
addToDeadNodes() while InvalidEncryptionKeyException happens in
fetchBlockByteRange)

> Key: HDFS-5766
> URL: https://issues.apache.org/jira/browse/HDFS-5766
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 3.0.0
> Reporter: Liang Xie

> Found this issue when i read fetchBlockByteRange code:
> If we hit InvalidEncryptionKeyException, current logic is:
> 1) reduce the retry count
> 2) clearDataEncryptionKey
> 3) addToDeadNodes
> 4) retry in another loop...
> If i am correct, we should treat InvalidEncryptionKeyException similar with
> InvalidBlockToken branch, bypassing addToDeadNodes(), since it's a client
> related, not caused by DN side:)
