Re: runtime.resourcemanager


Have you checked task managers logs?

Hello Piotrek,

thank you for your answer. I installed a Flink on a local cluster and used the GUI in order to monitor the task managers. It seems the program does not start at all. The whole time just the job manager is struggling... For very very toy examples, after a long time (during this time I see the job manager logs as I mentioned before),  the job is started and can be executed in 2 seconds.

Please investigate logs/standard output/error from the task manager that has failed (the logs that you showed are from job manager). Probably there is some obvious error/exception explaining why has it failed. Most common reasons:
- out of memory
- long GC pause
- seg fault or other error from some native library
- task manager killed via for example SIGKILL

Hello all,

I have an algorithm x () which contains several joins and usage of 3 times of gelly ConnectedComponents. The problem is that if I call x() inside a script more than three times, I receive the messages listed below in the log and the program is somehow stopped. It happens even if I run it with a toy example of a graph with less that 10 vertices. Do you have any clue what is the problem?
