Hello Mike Percy, Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/4338
to look at the new patch set (#2).
Change subject: rpc: print nicer errors when mixing up HTTP and KRPC
......................................................................
rpc: print nicer errors when mixing up HTTP and KRPC
Users often accidentally try to navigate to a Kudu server's RPC port in
their browser, or try to send an RPC to the HTTP port. This patch
improves the error messages that are reported as follows:
* Clients trying to speak RPC to the HTTP port now see an error like:
F0908 16:08:15.823751 21988 kudu-admin.cc:168] Check failed: _s.ok() Bad
status: IO error: Could not locate the leader master: Client connection
negotiation failed: client connection to 127.0.0.1:8051: received
invalid RPC message which appears to be an HTTP response. Verify that
you have specified a valid RPC port and not an HTTP port.
instead of
F0908 16:09:42.489558 22016 kudu-admin.cc:168] Check failed: _s.ok() Bad
status: IO error: Could not locate the leader master: Client connection
negotiation failed: client connection to 127.0.0.1:8051: Received
invalid message of size 1213486160 which exceeds the
rpc_max_message_size of 52428800 bytes
* Servers which receive an HTTP request to their RPC port now report an
error like:
0908 16:06:22.975401 (+ 68us) negotiation.cc:234] Negotiation
complete: Invalid argument: Server connection negotiation failed: server
connection from 127.0.0.1:56866: invalid negotation, appears to be an
HTTP client on the RPC port
instead of:
0908 16:04:47.236063 (+ 88us) negotiation.cc:234] Negotiation
complete: Invalid argument: Server connection negotiation failed: server
connection from 127.0.0.1:56832: Connection must begin with magic
number: hrpc
