> Project: HBase
> Issue Type: Bug
> Components: rpc
> Reporter: Duo Zhang

> Priority: Major
>
> Found this when implementing HBASE-25051.
> Basically there are 2 problems:
> # IPCUtil.isFatalConnectionException only checks whether class name matches,
> so if we use a sub class for FatalConnectionException, it will return false
> which makes the logic incorrect.
> # In BlockingRpcConnection, we will first check whether there is a call with
> the id but since we will pass -1 as call id for bad preamble header, we will
> return earlier without actually checking the error response.
> This will not introduce big trouble in production as the call will still fail
> with connection closed exception, but still worth to fix, anyway.
