Is it possible to configure hdfs in a federation mode and in an HA
mode in the same time?
Hello all,
I don't understand if it possible to configure HDFS in both modes in the
same time. Does it make sense? Can somebody show a simple configuration of
HDFS in both modes? (nameNode1, nameNode2, nameNodeStandby1,
nameNodeStandby2)
Sincerely,
Alexandr

Hello Rakesh,
Thank you for your help. I will try to configure a cluster and will respond
later about it.
Best regards,
Alexandr

Yes, it is possible is to enable HA mode and Automatic Failover in
a federated namespace. Following are some of the quick references, I feel
its worth reading these blogs to get more insight into this. I think, you
can start prototyping a test cluster with this and post your queries to
this forum if you face any issues while setting up, some of us will help
you.
