    Re: Cassandra Database Error

    I've a four node apache cassandra community 1.2 cluster in single datacenter with a seed.
    All configurations are similar in cassandra.yaml file.
    The following issues are faced, please help.

    1] Though fourth node isn't listed in nodetool ring or status command, system.log displayed only this node isn't communicating via gossip protoccol with other nodes.
    However both jmx & telnet port is enabled with proper listen/seed address configured.

    2] Though Opscenter is able to recognize all four nodes, the agents are not getting installed from opscenter.
    However same JVM version is installed as well as JAVA_HOME is also set in all four nodes.

    Further observed that problematic node has Ubuntu 64-Bit & other nodes are Ubuntu 32-Bit, can it be the reason?
