Subject Externalized checkpoints and metadata
Date Wed, 25 Apr 2018 13:07:47 GMT
Hello,

We are trying to use externalized checkpoints, using RocksDB on Hadoop hdfs.
We would like to know what is the proper way to resume from a saved checkpoint as we are currently
running many jobs in the same flink cluster.

The problem is that when we want to restart the jobs and pass the metadata file (or directory)
there is 1 file per job but they are not easily identifiable based on the name:
Example
/checkpoints/checkpoint_metadata-69053704a5ca
/checkpoints/checkpoint_metadata-c7c016909607

We are not using savepoints and reading the documentation I see there are 2 ways to resume,
1 passing the metadata file (not possible as we have many jobs) and the other passing the
directory,
But by default it looks for a _metadata file which doesn’t exist.

Thank you,
Juan G.
