Node not starting and waiting for ever
Hi,
We are trying to start the Ignite node on spark worker node. When i try to
start 10 nodes, few starts and few not and its in hung state.
The log shows non heap free -1% and the log is below. Any clue whats
happening and how to fix this ?

Hi,
The metrics are appear with specific frequency[1], and it does not mean the
node a hung. This is normal behavior.
About the row:
^-- Non heap [used=137MB, free=-1%, comm=139MB]
If the JVM non-heap memory size is unlimited, the free size is showing "-1".
Why are you think this nodes did not started?
