The client should be able to use multiple remote DN interfaces for block
transfer
---------------------------------------------------------------------------------
Key: HDFS-3218
URL: https://issues.apache.org/jira/browse/HDFS-3218
Project: Hadoop HDFS
Issue Type: Sub-task
Components: hdfs client
Reporter: Eli Collins
Assignee: Eli Collins
HDFS-3146 and HDFS-3216 expose multiple DN interfaces to the client. In order
for clients, in aggregate, to use multiple DN interfaces clients should pick
different interfaces when transferring blocks. Given that we cache client <->
DN connections the policy of picking a remote interface at random for each new
connection seems best (vs round robin for example). In the future we could make
the client congestion aware. We could also establish multiple connections
between the client and DN and therefore use multiple interfaces for a single
block transfer. Both of those are out of scope for this jira.
