Subject [jira] [Commented] (HBASE-11058) call_id seems never present in response
Date Tue, 29 Apr 2014 04:08:15 GMT

stack commented on HBASE-11058:
-------------------------------

I took a quick look w/ wire shark and seem to be able to match up a few requests and responses
via their call_id.

Below is an isMasterRunning

00:00:00:17:15:08:02:1a:0f:49:73:4d:61:73:74:65:72:52:75:6e:6e:69:6e:67:20:01:00
00:00:00:06:02:08:02:02:08:01

See how the id matches request/response 08:02.

This is the next call... getTableNames:

00:00:00:15:13:08:03:1a:0d:47:65:74:54:61:62:6c:65:4e:61:6d:65:73:20:01:00
00:00:00:1a:02:08:03:16:0a:14:0a:07:64:65:66:61:75:6c:74:12:09:54:65:73:74:54:61:62:6c:65

08:03

Here is a scan meta:

00:00:00:12:0a:08:0c:1a:04:53:63:61:6e:20:01:06:18:1c:20:00:28:01
00:00:00:08:02:08:0c:04:10:1c:18:00

08:0c

08 is the field number #1 right shifted by 3 and the type is 0 (uint3).  The value is 0xc,
a varint: https://developers.google.com/protocol-buffers/docs/encoding

Could you be matching the wrong response?
