Hi,
Like it says, these are warnings.
Warning 1: This means that a lock couldn't be acquired when starting a
check-pointing operation.
This operation will be re-tried. see:
https://apacheignite.readme.io/docs/persistence-checkpointing
Warning 2: This means that the continuous query you are subscribing to
sent an update to the listener
but did not get an acknowledgement within 100ms. Check
that the network is working correctly
and that all your continuous query updates have reached
their destinations.
Thanks, Alex
