When the ray cluster runs for a long time or execute many tasks, log files can be large, such as monitor.err, full of could not find ip for client xxxx.

Targetting 4.1

Proposal

Take the existing:

hazelcast/hazelcast/src/main/java/com/hazelcast/map/impl/proxy/MapProxyImpl.java

Line 916 in 4fed159

 public <R> Iterator<R> iterator(int fetchSize, int partitionId, Projection<Map.Entry<K, V>, R> projection, 

And create a public API in IMap which differs from the above in that it:

1. does not require partitionId but work

See optuna/optuna#1913.

Some type hints are not complying to the latest mypy == 0.790 and should be addressed.

In osx/updater/updater.go, we're referencing an ancient Go package, which has moved to a new location. Right now, the updater doesn't build (should we test this on travis?).

Most of the functionality we used from Guava are provided by the JDK by now.
The stuff that is missing from the JDK has mostly been added in the utilities we inherited from Elasticsearch, due to their decision to remove Guava completely.
Any functionality that we use which isn't present in the JDK can be co
