------------------------------------------------------------------
There is a pattern:
For successful tests there are logs in artifacts on TC
(run via shell
??Starting remote node with SSH command: nohup
"/data/teamcity/work/fe52c920c1589f47/bin/ignite.sh" v
"modules/core/src/test/config/spring-start-nodes.xml"
-J-DIGNITE_SSH_HOST="127.0.0.1" -J-DIGNITE_SSH_USER_NAME="teamcity" >
/data/teamcity/work/fe52c920c1589f47/work/log/ignite-startNodes/05-16-2018-13-13-47-6c1e5bff.log
2>& 1 &??
For every failing tests however the log file is absent. Since this is stderr
redirection and the file is just absent I guess the error is very high up stack
(may be during this shell command invocation, for example).
In any case given that remote nodes are failing without any error logs I am not
sure this problem is traceable at all unless we change something in tests or
Teamcity configuration.
