                How to Reset Kafka Consumer Group Offset
              
          
    Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe
Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

Reset the consumer offset for a topic (preview)

## ducks.sh
du -cks * | sort -rn | head -11

# Usually set this up in my bash profile as an alias:

# alias ducks='du -cks * | sort -rn | head -11'

# Because it is fun to type ducks on the command line. :)

                Cassandra unsafe assassinate - removing a dead node from the cluster
              
          
    Unsafe Node Assassinate

On Cassandra 1.1.x, nodetool removetoken  on a dead node hangs. The only way to reliably remove the node
from the cluster is to use an undocumented JMX command to force the remove of the node from gossip.
Upgrading to 1.2.x and above should obviate these steps in favor of nodetool removenode - See 1.2 Docs
It's probably also a good idea to run a nodetool repair after this operation - See wiki
