Subject Re: change cluster name retaining keypsace
Date Thu, 10 Jan 2013 03:36:12 GMT
Hello,

And thanks for your reply! Well so far it's just a single node. So I
wouldn't think this should be so complicated. But one day hopefully from
this node a cluster will grow, but that we shall have to wait and see.

At any rate, at /var/log/cassandra I don't see a directory called system.
All I see is a system log (a bunch of them rotated, I won't show the
rotated logs:

[root@beta:~] #ls -l /var/log/cassandra/system.log
-rw-r--r-- 1 root root 12003809 Jan  9 22:29 /var/log/cassandra/system.log

The only LocationInfo files I see pertaining to cassandra are here:

[root@beta:~] #locate LocationInfo | grep -i  -v -e backup -e nagios
/var/lib/cassandra/data/system/LocationInfo-hd-249-Data.db
/var/lib/cassandra/data/system/LocationInfo-hd-249-Digest.sha1
/var/lib/cassandra/data/system/LocationInfo-hd-249-Filter.db
/var/lib/cassandra/data/system/LocationInfo-hd-249-Index.db
/var/lib/cassandra/data/system/LocationInfo-hd-249-Statistics.db
/var/lib/cassandra/data/system/LocationInfo-hd-250-Data.db
/var/lib/cassandra/data/system/LocationInfo-hd-250-Digest.sha1
/var/lib/cassandra/data/system/LocationInfo-hd-250-Filter.db
/var/lib/cassandra/data/system/LocationInfo-hd-250-Index.db
/var/lib/cassandra/data/system/LocationInfo-hd-250-Statistics.db
/var/lib/cassandra/data/system/LocationInfo-hd-251-Data.db
/var/lib/cassandra/data/system/LocationInfo-hd-251-Digest.sha1
/var/lib/cassandra/data/system/LocationInfo-hd-251-Filter.db
/var/lib/cassandra/data/system/LocationInfo-hd-251-Index.db
/var/lib/cassandra/data/system/LocationInfo-hd-251-Statistics.db

Not sure what the effect of removing these files would be, but would doing
so  allow me to change my cluster name while retaining my keyspace schema?

Thanks!

Tim
