    Hi,

    In case the namenode goes down, what is the mechanism provided for business continuity in Hortonworks ?
    How to bring the name node up so that HBase remains up through out ?

    Regds,
    Samir

    Hi Samir,

    For HBase to remain up throughout a namenode failure you will need to have set up a HIgh Availability cluster. In such a cluster once it is sensed that the namenode is failing the system will seamlessly switch to using the backup.

    Thanks,
    Ted.
