> TestRPCCompatibility can fail intermittently with errors like the following when tests are not run in declaration order:
> {noformat}
> testVersion2ClientVersion1Server(org.apache.hadoop.ipc.TestRPCCompatibility): expected:<3> but was:<-3>
> {noformat}
> Moving the reset of the ProtocolSignature cache from ad-hoc usage in testVersion2ClientVersion2Server to tearDown fixes the issue.
