title: databricks-connect failed to connect to Databricks cluster runtime 8.4
body: <p>I have the following setup</p>
  <p>Databricks Cluster:</p>
  <pre><code>8.4 ML (includes Apache Spark 3.1.2, Scala 2.12)
  </code></pre>
  <p>Client side:</p>
  <pre><code>databricks==0.2
  databricks-cli==0.14.3
  databricks-connect==8.1.10 (The latest version up to date 20210813)
  </code></pre>
  <p>When I run <code>databricks-connect test</code> to test the connection, I got this error message</p>
  <pre><code>java.lang.IllegalArgumentException: 
  The cluster is running server version `dbr-8.4` but this client only supports Set(dbr-8.1). 
  You can find a list of client releases at https://pypi.org/project/databricks-connect/#history, and install the right client version with `pip install -U databricks-connect==&lt;version&gt;`. 
  For example, to install the latest 5.1 release, use `pip install -U databricks-connect==5.1.*`. 
  To ignore this error and continue, set DEBUG_IGNORE_VERSION_MISMATCH=1.
  </code></pre>
  <p>According to the error message, I understand there is a compatibility issue with the client and server versions. However, I am already using the latest client.</p>
  <ol>
  <li>Does it mean the client doesn't add support for server version 8.4?</li>
  <li>Is there any way to circumvent this issue?</li>
  </ol>
