Description

ZooKeeper, by default binds to all interfaces. This can cause issues, and can be quite slow when IPv6 is enabled. MiniAccumuloCluster can set the clientPortAddress explicitly in the zoo.cfg file to ensure it binds to the IPv4 loopback on the localhost 127.0.0.1.

Additionally, a configuration option could be added to MiniAccumuloConfig to be able to configure the bind address, and simply default to 127.0.0.1.

Another option to pursue is any JVM settings that might restrict ZooKeeper to IPv4 only during the build tests.
