Hi,
I have a single master-slave replication configuration going, but I am
running into issues where I end up with two live servers when I bring down
the original master. This is being ran in a Kubernetes cluster using static
connectors, but regardless, the behavior is not what I expected.
Basically what is happening is, master-slave configuration is set correctly
and then I bring down the master. The slave becomes the live server, but
when the original master comes back up, the slave(which is now the live)
doesn't register that the master came back up and doesn't fail over and now
there ends up being two live servers. Perhaps it has something to do with
the fact that it is running in a Kubernetes environment?
Here are my configurations for my master-slave:
MASTER.XML
<core xmlns="urn:activemq:core" xsi:schemaLocation="urn:activemq:core

<connector

</connectors>
<ha-policy>

Any help with this would be greatly appreciated!
