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..

We should probably remove that, or at least document it. The upgrade
facility is for upgrading from version 2 to version 3. There is no
need to run upgrade if upgrading a minor/fix version.

Re-read my previous email "is for upgrading from version 2 to version
3". Perhaps I wasn't clear enough - if you are upgrading from version
2.x.x to version 3.x.x then you should use the upgrade utility. Your
latest response is a minor upgrade, no need to run the utility for
that.
