I'm trying to use sstable2json in 2.1.6 installation. Note that I'm using the tool from the tarball since the Ubuntu package does not include it. I'm seeing the following error message:
./sstable2json /var/lib/cassandra/data/audits/audits_by_user/audits-audits_by_user-ka-38156-Data.db Filename /var/lib/cassandra/data/audits/audits_by_user/audits-audits_by_user-ka-38156-Data.db references to nonexistent keyspace: audits! The audits keyspace certainly does exist. Google didn't turn anything up besides source code hits, not sure what's going on here. The only unusual thing is that 2.1 names tables with a hex string at the end (e.g. audits_by_user-63726570f03211e4aa12c5f122268031) but since we have existing data it still lives in audits_by_user with no hex string.
