Key: HBASE-16670
URL: https://issues.apache.org/jira/browse/HBASE-16670
Project: HBase
Issue Type: Bug
Reporter: Yu Li
Assignee: Yu Li
Priority: Minor
Currently in {{RpcServer#processRequest}}, we will check whether the request
header has parameters but missed handling the abnormal case, so if there's no
param in the header, it will throw NPE like below:
