 To build a release of PQS which packages a specific version of Phoenix, specify the `package-phoenix-client` system property
 and specify the `phoenix.version` system property to indicate a specific Phoenix version, as well as
 the `phoenix.client.artifactid` to choose the phoenix-client HBase variant.
+You need to bundle the embedded client variant, to avoid conflicts with the logging libraries.
