Thanks for quick answer.
We have fully working HDP 2.0.9 stack on our test environment with NameNode HA. If first of NN is in active state and will fall the other will take his place and will change state from standby to active.
My question is regarding to HA of NN from client side. I mean if we have client host with client libraries and accessing first of NN, we have to detect first NN has fall and switch to second NN manually? Is there any proxy or something like that? Is there automatic process that will let client host know about stop using fallen NN and start using the second one?
Thanks for answer.
