HBASE-25292 Improve InetSocketAddress usage discipline (#2669)
Network identities should be bound late. Remote addresses should be resolved at the last possible moment, just before connect(). Network identity mappings can change, so our code should not inappropriately cache them. Otherwise we might miss a change and fail to operate normally. Revert "HBASE-14544 Allow HConnectionImpl to not refresh the dns on errors" Removes hbase.resolve.hostnames.on.failure and related code. We always resolve hostnames, as late as possible. Preserve InetSocketAddress caching per RPC connection. Avoids potential lookups per Call. Replace InetSocketAddress with Address where used as a map key. If we want to key by hostname and/or resolved address we should be explicit about it. Using Address chooses mapping by hostname and port only. Add metrics for potential nameservice resolution attempts, whenever an InetSocketAddress is instantiated for connect; and metrics for failed resolution, whenever InetSocketAddress#isUnresolved on the new instance is true. * Use ServerName directly to build a stub key * Resolve and cache ISA on a RpcChannel as late as possible, at first call * Remove now invalid unit test TestCIBadHostname We resolve DNS at the latest possible time, at first call, and do not resolve hostnames for creating stubs at all, so this unit test cannot work now.
