Hi,

Just log into the machine and check it’s memory consumption using htop or a 
similar tool under the load. Remember about subtracting Flink’s memory usage 
and and file system cache.

Set heap size

2017-10-19 Thread AndreaKinn 
About task manager heap size Flink doc says:

... If the cluster is exclusively running Flink, the total amount of
available memory per machine minus some memory for the operating system
(maybe 1-2 GB) is a good value

But my nodes have 2GB of ram each. There isn't an empirical count to set ram
memory or a way to estimate the ram used by the OS?
