• couchbase error: the error could be the initial bucket not being properly loaded when I call the subsequent methods, as there is a BUCKET_OPEN_IN_PROGRESS, added a waitUntilReady to try to fix it

• ldap error: not sure why it only appeared now, but changed localhost to GenericContainer.getHost(), as the docker server may not be on 127.0.0.1 using TeamCity

• hdfs error, looks like the hdfs/hadoop folder is corrupted for some reason, replaced the path with a TemporaryFolder

- Also, updated test container version like the Core one
