Hi Todd,

My cluster still in preproduct= ion state, so I just drop all data/metadata. My team will try to use Kudu o= n production with a 20-40 TB of data, so I will be happy to see any closed = tickets about operation stuff in next releases :).

Hey Pavel,

Did you find a workarou= nd for this? As you found it's not something we support easily today, b= ecause each server will "remember" the old host names of all of i= ts replication peers within its consensus metadata, and continue to try to = talk to them after a restart. Renaming hosts would involve writing the cons= ensus metadata files on all of the servers with the updated names.

We're soon facing this same issue with one of the test= clusters at Cloudera, so I'm guessing we'll have to write some kin= d of tool to get it back online as well :) Would be curious to hear what ap= proach you took.

-Todd
