hi folks, how to use a bolt to write data to hbase which use kerberos as secure mechanism, is there some best practice or example to share with?
maybe we can use keytab in topology's bolt, but this has two problems: 1. if the cluster has multiple topologies for different users, we must deploy many keytab for the storm cluster. 2. using keytab in topology's bolt, it make effect in task level, actually, this method do kerberos authentication many times(equals the number of tasks), yet we just need do the kerberos authentication in worker (process) level for one time. so any idea to share ?
