-<h1 id="debugging-and-common-error-messages">Debugging and Common Error Messages</h1>
-
-<h2 id="i-have-a-notserializableexception">I have a NotSerializableException.</h2>
-
-<p>Flink uses Java serialization to distribute copies of the application logic (the functions and operations you implement,
-as well as the program configuration, etc.) to the parallel worker processes.
-Because of that, all functions that you pass to the API must be serializable, as defined by
-<a href="http://docs.oracle.com/javase/8/docs/api/java/io/Serializable.html">java.io.Serializable</a>.</p>
-
-<p>If your function is an anonymous inner class, consider the following:</p>
-
-<ul>
- <li>Make the function a standalone class, or a static inner class.</li>
- <li>Use a Java 8 lambda function.</li>
-</ul>
-
-<p>If your function is already a static class, check the fields that you assign when you create
-an instance of the class. One of the fields most likely holds a non-serializable type.</p>
-
-<ul>
- <li>In Java, use a <code>RichFunction</code> and initialize the problematic fields in the <code>open()</code> method.</li>
- <li>In Scala, you can often simply use “lazy val” to defer initialization until the distributed execution happens. This may come at a minor performance cost. You can naturally also use a <code>RichFunction</code> in Scala.</li>
-</ul>
-
-<h2 id="using-the-scala-api-i-get-an-error-about-implicit-values-and-evidence-parameters">Using the Scala API, I get an error about implicit values and evidence parameters.</h2>
-
-<p>This error means that the implicit value for the type information could not be provided.
-Make sure that you have an <code>import org.apache.flink.streaming.api.scala._</code> (DataStream API) or an
-<code>import org.apache.flink.api.scala._</code> (DataSet API) statement in your code.</p>
-
-<p>If you are using Flink operations inside functions or classes that take
-generic parameters, then a TypeInformation must be available for that parameter.
-This can be achieved by using a context bound:</p>
-
-<div class="highlight"><pre><code class="language-scala"><span class="k">def</span> <span class="n">myFunction</span><span class="o">[</span><span class="kt">T:</span> <span class="kt">TypeInformation</span><span class="o">](</span><span class="n">input</span><span class="k">:</span> <span class="kt">DataSet</span><span class="o">[</span><span class="kt">T</span><span class="o">])</span><span class="k">:</span> <span class="kt">DataSet</span><span class="o">[</span><span class="kt">Seq</span><span class="o">[</span><span class="kt">T</span><span class="o">]]</span> <span class="k">=</span> <span class="o">{</span>

-
-<h2 id="i-see-a-classcastexception-x-cannot-be-cast-to-x">I see a ClassCastException: X cannot be cast to X.</h2>
-
-<p>When you see an exception in the style <code>com.foo.X</code> cannot be cast to <code>com.foo.X</code> (or cannot be assigned to <code>com.foo.X</code>), it means that
-multiple versions of the class <code>com.foo.X</code> have been loaded by different class loaders, and types of that class are attempted to be assigned to each other.</p>
-
-<p>The reason for that can be:</p>
-
-<ul>
- <li>
- <p>Class duplication through <code>child-first</code> classloading. That is an intentional mechanism to allow users to use different versions of the same
-dependencies that Flink uses. However, if different copies of these classes move between Flink’s core and the user application code, such an exception
-can occur. To verify that this is the reason, try setting <code>classloader.resolve-order: parent-first</code> in the configuration.
-If that makes the error disappear, please write to the mailing list to check if that may be a bug.</p>
- </li>
- <li>
- <p>Caching of classes from different execution attempts, for example, by utilities like Guava’s Interners, or Avro’s Schema cache.
-Try to not use interners, or reduce the scope of the interner/cache to make sure a new cache is created whenever a new task
-execution is started.</p>
- </li>
-</ul>
-
-<h2 id="i-have-an-abstractmethoderror-or-nosuchfielderror">I have an AbstractMethodError or NoSuchFieldError.</h2>
-
-<p>Such errors typically indicate a mix-up in some dependency version. That means a different version of a dependency (a library)
-is loaded during the execution compared to the version that code was compiled against.</p>
-
-<p>From Flink 1.4.0 on, dependencies in your application JAR file may have different versions compared to dependencies used
-by Flink’s core, or other dependencies in the classpath (for example from Hadoop). That requires <code>child-first</code> classloading
-to be activated, which is the default.</p>
-
-<p>If you see these problems in Flink 1.4+, one of the following may be true:</p>
-
-<ul>
- <li>You have a dependency version conflict within your application code. Make sure all your dependency versions are consistent.</li>
- <li>You are conflicting with a library that Flink cannot support via <code>child-first</code> classloading. Currently these are the
-Scala standard library classes, as well as Flink’s own classes, logging APIs, and any Hadoop core classes.</li>
-</ul>
-
-<h2 id="my-datastream-application-produces-no-output-even-though-events-are-going-in">My DataStream application produces no output, even though events are going in.</h2>
-
-<p>If your DataStream application uses <em>Event Time</em>, check that your watermarks get updated. If no watermarks are produced,
-event time windows might never trigger, and the application would produce no results.</p>
-
-<p>You can check in Flink’s web UI (watermarks section) whether watermarks are making progress.</p>
-
-<h2 id="i-see-an-exception-reporting-insufficient-number-of-network-buffers">I see an exception reporting “Insufficient number of network buffers”.</h2>
-
-<p>If you run Flink with a very high parallelism, you may need to increase the number of network buffers.</p>
-
-<p>By default, Flink takes 10% of the JVM heap size for network buffers, with a minimum of 64MB and a maximum of 1GB.
-You can adjust all these values via <code>taskmanager.network.memory.fraction</code>, <code>taskmanager.network.memory.min</code>, and
-<code>taskmanager.network.memory.max</code>.</p>
-
-<p>Please refer to the <a href="http://ci.apache.org/projects/flink/flink-docs-master/ops/config.html#configuring-the-network-buffers">Configuration Reference</a> for details.</p>
-
-<h2 id="my-job-fails-with-various-exceptions-from-the-hdfshadoop-code-what-can-i-do">My job fails with various exceptions from the HDFS/Hadoop code. What can I do?</h2>
-
-<p>The most common cause for that is that the Hadoop version in Flink’s classpath is different from the
-Hadoop version of the cluster you want to connect to (HDFS / YARN).</p>
+<h1 id="common-error-messages">Common Error Messages</h1>
-<p>The easiest way to fix that is to pick a Hadoop-free Flink version and simply export the Hadoop path and
-classpath from the cluster.</p>
+<p>Common error messages are listed on the <a href="/gettinghelp.html#got-an-error-message">Getting Help</a> page.</p>
