Only get "manifest.json" and "ring" in my backups about cassandra_snapshotter

[tbarbugli]

what version of cassandra are you running?

Hi :)

Trying to get this to work on my EC2 instance...

When I run cassandra-snapshotter on my instance, I get the following
output:

[x.x.x.x] Executing task 'node_start_backup'
[x.x.x.x] Executing task 'upload_node_backups'
[x.x.x.x] sudo: cassandra-snapshotter-agent create-upload-manifest --manifest_path=/tmp/backupmanifest --snapshot_name=20140724110014 --snapshot_keyspaces= --snapshot_table= --data_path=/var/lib/cassandra/data/

[x.x.x.x] out: Requested clearing snapshot for: all keyspaces
[x.x.x.x] out:

[x.x.x.x] sudo: /usr/bin/nodetool ring

And then it exits after a few seconds (code 0).

On S3, it creates folders, but the only two files it puts there are
"manifest.json" and "ring". There are no backup files.

incremental_backups is enabled in cassandra.yaml, and JNA is also
installed.

Adding --new-snapshot doesn't help.

Am I just being retarded here or is something wrong?

Thanks :)

did you try to back up a single keyspace?

Yes, I tried that as well with the same result.

Any other ideas?

Anything I can do to get some log output or something that might help?

[tbarbugli]

what's the cassandra's data path? perhaps you use something else than the
standard /var/lib?

That's correct, I have it in /mnt/cassandra :)

I'll try symlinking /var/lib/cassandra => /mnt/cassandra and see what happens.

the cassandra data path is configurable; you can send a parameter to the
snapshot command (--cassandra-data-path)
I am going to create an issue about this problem; debugging this should be
easier than this.

Indeed that did the trick! Thanks! :)

Cool about the parameter, hadn't seen that.

Thanks again :)

Actually, on further inspection, the --cassandra-data-path option has no effect.

The only way I can get the snapshotter to actually back up my data on /mnt/cassandra is by symlinking to it from /var/lib/cassandra
