Subject Re: Renaming hostname of tserver/master
Date Mon, 05 Feb 2018 15:52:09 GMT
Hi Todd,

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