to look at the new patch set (#4).
Change subject: Support location awareness in READ_CLOSEST for the C++ client
......................................................................
Support location awareness in READ_CLOSEST for the C++ client
Previously, in READ_CLOSEST, the C++ client would choose to read from a
local tablet server if possible and otherwise pick a random replica.
This changes and enhances READ_CLOSEST mode to work as follows:
1. If there is a local server, use it. If there are multiple local
servers, choose one at random.
2. If there is a server in the same location as the client, use it. If
there are multiple servers in the same location, choose one at
random.
3. Otherwise, choose a server at random.
This is not a breaking change, as in the absence of locations the
behavior is consistent with what was documented before, which was only
that a local server would be chosen if possible, else a random server.
