ERROR while creating save points..

Sathi Chowdhury

Hi Flink Dev,

I am running flink on yarn from EMR and I was running this command to test an external savepoint

flink savepoint 8c4c885c5899544de556c5caa984502d  /mnt

 

 

The program finished with the following exception:

Any clue what’s wrong?

I was able to bypass that one ..by running it from bin/flink …

Now encountering

by: java.lang.NullPointerException: Checkpoint properties say that the checkpoint should have been persisted, but missing external path.

Till Rohrmann
Hi Sathi,

this looks not right on the first glance. Could you please share the exact command you've used to trigger a savepoint and also the full stack trace of the exception?

Cheers,
Till
