Support sending priority RPC
----------------------------
Key: HADOOP-6952
URL: https://issues.apache.org/jira/browse/HADOOP-6952
Project: Hadoop Common
Issue Type: Improvement
Components: ipc
Reporter: dhruba borthakur
Assignee: dhruba borthakur
There are certain class of RPCs that need priority delivery. This applies
especially to heartbeat RPCs that distributed systems (like HDFS) uses. Ability
to deliver heartbeat RPCs earlier than other data-movement RPCs can improve the
scalability of large scale distributed systems.
