Subject Support for multiple slots per task manager in Flink 1.5
Date Wed, 05 Dec 2018 11:41:19 GMT

According to the Flink 1.5 release docs multiple slots per task manager are
"not fully supported yet". Can you provide more information about what are
the risks of running more than one slot per tm?
We are running Flink on EMR on YARN. Previously we run 4 task task managers
with 8 slot each now we are running 32 with 1 slot each. However, since we
upgraded to Flink 1.5 we started seeing timeouts taking a connection from
AWS S3 SDK pool etc.
