Hi all,
I am trying one simple upgrade scenario.
Existing version : zookeeper-3.4.2
New version : zookeeper-3.4.3
While giving the command i am getting the given exception !
Note:
For the zookeeper 3.4.2 i configured only datadir.. so snapshot dir is also
using this dir..
Installed zookeeper 3.4.3 in another directory and giving the old datadir for
upgrade..
Am i missing some steps ?
I could not find the information for upgrade steps anywhere !
Pls help me to continue..
