FAQ
Hi,

We are running a 5 machine Hbase cluster. We have noticed that whenever an
HQuorum fails in one machine, the entire application that is running on
HBase crashes. Is there anything to do about this?

    What is an HQuorum?

    If you mean a regionserver then possibly you application is attempting to get data that was on a region hosted by the failed regionserver and in that case you need to make sure you application can deal the connection failure and wait for the the regions to be reassigned to another regionserver.

    Hi,
    Thanks for your reply. So does HBase automatically reassign to another
    regionserver or do we have to do it manually.

    It does it automatically.
