Oleg Ignatenko updated IGNITE-9585:
-----------------------------------
Ignite Flags: (was: Docs Required)
> Error message sometimes refers nonexisting log file when remote node fails to
> start
> -----------------------------------------------------------------------------------
>
> Key: IGNITE-9585
> URL: https://issues.apache.org/jira/browse/IGNITE-9585
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.6
> Reporter: Oleg Ignatenko
> Assignee: Oleg Ignatenko
> Priority: Minor
>
> Teamcity build logs sometimes refer to remote node log files that aren't
> present in build artifacts
> ([example|https://ci.ignite.apache.org/viewLog.html?buildTypeId=IgniteTests24Java8_StartNodes&buildId=1849937&branch_IgniteTests24Java8_StartNodes=%3Cdefault%3E]).
> I managed to reproduce this on my machine (details below) and it looks like
> typically the root cause of this is error message from
> [StartNodeCallableImpl|https://github.com/apache/ignite/blob/master/modules/ssh/src/main/java/org/apache/ignite/internal/util/nodestart/StartNodeCallableImpl.java]
> referring readers to file that doesn't exist (and it wasn't even created to
> start with).
> {code:java}
> return new ClusterStartNodeResultImpl(spec.host(), false, "Remote
> node could not start. " +
> "See log for details: " + scriptOutputPath);
> {code}
> This is quite painful when one tries to investigate node launching failures
> because the misleading message causes one to waste time investigating the
> problem that doesn't exist (it appears as if log file was there but somehow
> disappeared for some mysterious reason).
> ----
> To reproduce the issue locally one can do as follows: first, modify file
> [start-nodes-custom.sh|https://github.com/apache/ignite/blob/master/modules/core/src/test/bin/start-nodes-custom.sh]
> by replacing {{ignite.sh}} with the name of script that doesn't exist, eg
> {{noignite.sh}}. After that, execute unit test
> [IgniteProjectionStartStopRestartSelfTest|https://github.com/apache/ignite/blob/master/modules/ssh/src/test/java/org/apache/ignite/internal/IgniteProjectionStartStopRestartSelfTest.java]
> and study its results and logs.
> You will find that {{testCustomScript}} fails - which is expected because
> name of the script intended to be executed has changed to one that doesn't
> exist. Also you will find that log file for respective node hasn't been
> created - which is also expected because shell command fails before creating
> it. But in the same time test log will refer to mentioned file as if it
> exists.
