I have one Cassandra 1.0.9 server that is set up to be the seed

  • 0

I have one Cassandra 1.0.9 server that is set up to be the seed for a cluster. It has ~34gb of data on it. I am trying to join a second Cassandra 1.0.9 to the ring and have the first set up as the seed.

In /var/lib/cassandra/log/cassandra.log I am seeing:

INFO 20:06:52,809 JOINING: waiting for schema information to complete
INFO 20:07:22,815 JOINING: waiting for schema information to complete
INFO 20:07:52,817 JOINING: waiting for schema information to complete

INFO 20:11:22,847 JOINING: waiting for schema information to complete

In /var/log/cassandra/system log I am seeing:

Running a netstats gives me:

Responses                       n/a         0          51966

Any idea on how long this should take?

    It appears that I have resolved this with the following steps:

    1. Delete /var/lib/cassandra/data directory (and sub directories) on new server
    2. Delete /var/lib/cassandra/data/system/Schema* files on seed server
    3. Delete /var/lib/cassandra/data/system/Migration* files on seed server
    4. Recreate schema on seed server in cassandra-cli
    5. Start up Cassandra on new server

    Now I see the new server in the ring even though it is still joining ( it didn’t show up in ring on previous join attempts). Both the seed and new server are on the same Schema, as noted by running “describe cluster;” in cassandra-cli.

    I hope this helps someone else out in the future.
