Indeed I can confirm that I resolved this problem reducing the number of
slots per Task Manager (and thus incrementing the available memory of each
task)!
However from time to time I have serialization issue that I don't know
where they come from..it looks like the PjoSerialization has some issue

The job is running out of heap memory, probably because a user
function needs a lot of it (the parquet thrift sink?).
You can try to work around it by reducing the amount of managed memory
in order to leave more heap space available.

Hi to all,
running a job that writes parquet-thrift files I had this exception (in a
Task Manager):
io.netty.channel.nio.NioEventLoop - Unexpected
exception in the selector loop.
java.lang.OutOfMemoryError: Java heap space
