Hello Kudu Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/7177 to look at the new patch set (#2). Change subject: KUDU-2041: Fix negotiation deadlock ...................................................................... KUDU-2041: Fix negotiation deadlock With N threads in the negotiation threadpool, N or more concurrent client negotiation attempts could starve any incoming server negotiation tasks which used the same threadpool. If the set of negotiation attempts forms a graph with a N cycles, the negotiation could deadlock (at least until the negotiation timeout expires) as all nodes in the system wait for a server request to complete, but all nodes have dedicated all their resources to client requests. Fix: split the server and client tasks into two separate pools. Testing: add a unit test which reproduces the issue, and passes with the fix applied.
