Alexandr Kuramshin commented on IGNITE-8085:
--------------------------------------------
[~dpavlov], remote process startup procedure does the simple assumption -
{{SUCCESSFUL_START_MSG}} have to occurs in the startup log (remote process
output), so the local process wait for the occurrence scanning the log
{{NODE_START_CHECK_LIMIT}}-times with {{NODE_START_CHECK_PERIOD}}-delay. Remote
process may not had enougth time to finish startup sequence, making mistaken
failure. You may sure of that looking at the test run artifacts.
In such situations preferred to increase {{NODE_START_CHECK_LIMIT}}. Increasing
{{NODE_START_CHECK_PERIOD}} is not recommended as this lengthens successfully
ran tests.
> Flaky failures in Ignite Client Nodes test suite: Remote node could not
> start.
