Hi,
I'm running one Node embedded in my Java webapp and when it started
I'm running another node standalone and expect both nodes to be in one
cluster. When 2nd note is up the 1st node failed with
[java.lang.OutOfMemoryError: Java heap space] exception. I'm using
storage in memory, but the index is empty, so it's not because of
that. The error is raised in 100% of cases.
------------- 2nd node ----------------

Both nodes use the same config (YAML):

hosts : ["localhost:9300"]
index.storage.type: memory

Thank you!

Are they using the same version?

No, they were not. The 2nd node was of the version 0.9.
After upgrading it to version 0.10 the error has gone.
Thank you, Shay!
