I have a development machine that had a single-node Cassandra 2.1.2 setup. The main drive failed, but the secondary drive, mounted at /var, is good. I was able to connect this drive to another system with a working OS and Cassandra install and mount it.
I can see the files for my database under /var/cassandra/data// and would like to recover that data. Nothing outside of /var survived -- no configs or binaries.
Is it as simple as copying that directory to the /var/cassandra/data/ directory on the good system, or is there some other more detailed procedure for recovering/importing that data?
All you need to remember from your config files - is what was the partitioner. Now you should save your data files somewhere safe, create another single-node cluster, then follow the procedure described here.
The files in your saved data folder is what in these manuals is referred to as snapshot.
