TICKET = LI_DESCRIPTION = revert LI HOTFIX "Consumer should fetch metadata from the same broker until it is disconnected from that broker". since sticky metadata request is no longer needed. The original hotfix was introduced as a short term fix util the actual issue was found, and we no longer need this hotfix now. EXIT_CRITERIA = MANUAL ["after the original fix has been removed"]
…pache#4987) Implementation of KIP-302: Based on the new client configuration `client.dns.lookup`, a NetworkClient can use InetAddress.getAllByName to find all IPs and iterate over them when they fail to connect. Only uses either IPv4 or IPv6 addresses similar to the default mode.

…ltipleIPsWithUseAll (#116) TICKET = N/A LI_DESCRIPTION = The test fails since the domain kafka.apache.org used to return 3 IPs and is now only returning two IPs. Furthermore, the upstream fix identified below cannot be cleanly cherry picked. EXIT_CRITERIA = when the commit 131d475 is picked from upstream: KAFKA-12193: Re-resolve IPs after a client disconnects apache#9902
[LI-HOTFIX] Ignoring the failed tests (#188) TICKET = N/A LI_DESCRIPTION = Several tests are failing since the domain kafka.apache.org that used to resolve to more than 1 IPv4 addresses are not only resolving to 1 IPv4 address. The upstream code has overhauled the ClusterConnectionStatesTest. We are simply ignoring these tests for now, and will get the new logic from upstream after a major version rebase. EXIT_CRITERIA = This hotfix can be removed in the next major version rebase
…olvable (apache#6305) * Fix for KAFKA-7974: Avoid calling disconnect() when not connecting * Resolve host only when currentAddress() is called Moves away from automatically resolving the host when the connection entry is constructed, which can leave ClusterConnectionStates in a confused state. Instead, resolution is done on demand, ensuring that the entry in the connection list is present even if the resolution failed. * Add Javadoc to ClusterConnectionStates.connecting()
…lookup` (KIP-602) (apache#8644) This applies to the producer, consumer, admin client, connect worker and inter broker communication. `ClientDnsLookup.DEFAULT` has been deprecated and a warning will be logged if it's explicitly set in a client config.

…#329) The PR #228 attempted to resolve provided boostrap servers when the metadata is exceeding a staleness threshold. The config is coverred both on producer and consumer, and default behavior without configured value is setting timeout to Long.MAX_VALUE. However, cruise-control is affected by the behavior as it implements a similar mechanism on its own and directly uses of NetworkClient. The code would fail if empty bootstrap server is passed to NetworkClient, which is the case for internal use of CC. To resolve this, this patch aims to make default value as -1, and omit the code path referencing bootstrap server when we see -1. EXIT_CRITERIA = When #228 is ejected

use_all_dns_ips config has been backported from 3.0-li to 2.4-li and 2.3-li-1, and set as default. We would like the config to be adopted by LKC9 users, thus backport it to 2.0-li branch as well.
The config use_all_dns_ips was introduced in KIP-302 (apache#4987) and set as default in KIP-602 (apache#8644)
