Can you load one NN data (fsimage , edits..) to another NN?

[Yossi Ittach <yo...@gmail.com>]

Hey all

If I have 1 NN , can I transport it's data (copy) and start another NN with
it? it will bring me very close to creating a failover and failback
mechanisem.

Thanks!

Hi Yossi,

Yes you can start NN on different node using dfs.data.dir files.
set your dfs.data.dir config variable to point to this directory and you should be able to start NN on different node.
Try to search for previous discussions on this list regarding failover, lot of email and ideas have been recorded.

Thanks,
Lohit
