taskmanager.tmp.dirs vs io.tmp.dirs

[Flavio Pompermaier]

Hi to all,

looking at https://ci.apache.org/projects/flink/flink-docs-stable/ops/config.html it's not very clear to me the difference between these two settings (actually I always used the same value for the two).

My understanding is that taskmanager.tmp.dirs is used to spill memory when there's no more RAM available, while io.tmp.dirs for all other situations (but which are them exactly?). 

Thanks in advance,

Flavio

Hi Flavio,

taskmanager.tmp.dirs is the deprecated configuration key which has been superseded by the io.tmp.dirs configuration option. In the future, you should use io.tmp.dirs.

Cheers,

Hi,

I created FLINK-12460 to update the documentation.
