I'd recommend attaching the capture file to a Bugzilla ticket (with all of the
links mentioned here) and possibly your patch of the internal dissector.
Perhaps somebody can take it from there.
As a side note, I still don't know how I feel about dissectors being "pulled
from the wild" from developers rather than pushed to Wireshark (via Gerrit) by
the original author(s). Gerrit (and just Buzilla before that) isn't THAT hard
to navigate. Are we missing something? Are our code standards too strict?

Subject: [Wireshark-dev] hadoop dissector
Hi list
I opened a hadoop 2.6 capture file with the current master and I found that the
hadoop dissector fails in opening the file (wrong dissection). This is probably
related to the changes in the wire protocol that have not been reflected into
the current dissector. So I decided to start understading how the dissector
should be updated... but I stucked.
I can't find the specifications of the wire protocol. I just found this
https://wiki.apache.org/hadoop/HadoopRpc.
I've found this project https://github.com/liukeyou/hadoop-wireshark that,
from the screenshots, sound promising, but is for WS 1.10, and is a plugin for
windows (my dev env is linux). I succeded to compile it as internal dissector,
but nothing gets dissected. Maybe it looks for something somewhere that I
didn't copy.
I tried to compile hadoop myself, to instrument it in order to have a better
understand of the flow and of the protocol, but the high level of abstraction
of the hadoop java code made me lost.
These are my attempts so far... not very happy about them.
Did anyone tried to make the same or something different? Anyone having
links/resources/ideas to share? Anyone interested in working on it?
Cheers,
Dario
