Bharath Vissapragada updated HBASE-23804:
-----------------------------------------
Description:
Currently, master RPC server (*not* info server) always binds to the address
endpoint to which the default hostname of the server resolves to. However,
master registry picks the default end point to connect to as "localhost:16000"
when "hbase.masters" are not configured. This is leading to a mismatch because
the server may not be listening on the loopback address. This is a problem only
in the scripts (single proc/pseudo distributed modes) because these are the
cases in which "hbase.masters" is not populated by default.
The fix is to pick the service endpoint the same way the RPC server does it.
was:Currently master addr end point always defaults to localhost:16000 if
nothing is configured. This is not always correct, especially if the master rpc
end point binds to an address that is not loopback. The default behavior for
rpc server's bind address is to looks u the hostname and then bind to the
address to which it resolves. Master registry should do the same.
