Ivan Fedotov commented on IGNITE-8619:
--------------------------------------
[~ilantukh], In this PR I try to ensure that process of launching remote node
via ssh was really started [1]: for this I try to find in output message from
command info about new process [2] and set up timeout to exclude hangup of the
program.
Timeout was already used in channel session [4], so I didn't change value of
timeout and put it to separate method.
After that locally failures stopped, but they sometimes appeared on TC. I
suggested that there is not enough time for TC to start ssh connection and
session closed before it, so I increased amount of attempts in tests to connect
via ssh [5] (3 attempts).

> Now there is a problem with launch remote node via ssh. Initially was an
> assumption that it's due to remote process has not enough time to write
> information into log:
> [IGNITE-8085|https://issues.apache.org/jira/browse/IGNITE-8085]. But this
> correction didn't fix [TeamCity
> |https://ci.ignite.apache.org/project.html?projectId=IgniteTests24Java8&testNameId=6814497542781613621&tab=testDetails]
> (IgniteProjectionStartStopRestartSelfTest.testStartFiveNodesInTwoCalls).
> So it's necessary to make launch remote node via ssh always succesful.
