We currently run journalnodes together with datanodes and they share the same mount point for both the data dir and edits dir.
We ran into the issue where this shared mount point volume used for the datanode got full and thus the journal node was unable to start due to insufficient space. How would you go about where to place the journal node edits? Is it expected to grow very large and/or needs to be in a separate partition? Or can I use e.g. tmpfs for it? Our namespace of 1PB with 5 journal nodes sees the journal node edits size of about 5.4GB (on each journal node) Thanks for any tips and best practices.
