Help->Show Log doesn't show anything

Me again - tried to send you logs for the previous case, but Sho Log function doesn’t show anything.

i’ve found error.log which is 639mb and accumulates all errors for the last few years. maybe it make sense to have cyclic logs, i.e. 10 logs 10mb each and rotate.

the same applicable to warning.log.

Yes, that’s a good suggestion. [SPARK-1849] Make logs rotate based on size or time - IgniteRealtime JIRA
