-------------------------------------
Status: Patch Available (was: In Progress)
> Failure while connecting to zk if HBase is running in standalone mode in a
> container
> ------------------------------------------------------------------------------------
>
> Key: HBASE-27420
> URL: https://issues.apache.org/jira/browse/HBASE-27420
> Project: HBase
> Issue Type: Bug
> Components: Zookeeper
> Reporter: Sanjeet Malhotra
> Assignee: Sanjeet Malhotra
> Priority: Major
> Fix For: 3.0.0-alpha-4
>
>
> With [this change|https://issues.apache.org/jira/browse/HBASE-23993]
> zookeeper will only listen for client connections on 127.0.0.1 in standalone
> mode. If HBase is running in standalone mode inside a docker container and
> docker port forwarding is being used to connect to HBase inside container
> then, any client trying to connect to zk will have destination IP as
> container's private IP rather than loopback IP. This will cause zk to reject
> all client connections being initiated from outside the container.
> Thus, we need a way to make zk listen for client connections on IP other than
> loopback. zk already provides a property named `clientPortAddress` to specify
> the address to listen for client connections. And, we can specify zk
> properties using `hbase.zookeeper.property.` prefix. Thus, the proposal is to
> allow user to specify the IP address that zk will listen on using
> `hbase.zookeeper.property.clientPortAddress` and if its not specified then
> default to loopback as per current behaviour.
> This way, the tests will still remain unimpacted and HBase can also be used
> in standalone mode in a container.
