The error <code>self-suppression not permitted</code> is not the actual error here.

This error is thrown by JVM when runtime tries to throw multiple <code>THROWABLE</code> instance from code.

To do so, JDK-7 introduces the "suppressedExceptions" to Throwable to suppress previous exception and retain very recent exception.

So Java tries - <code>throwable.addSuppressed(throwable)</code> - which is invalid and Throwable instance itself throws the IllegalArgumentException and the real exception is lost this way.

<hr>

From this in log: <code>Caused by: java.io.IOException: All datanodes DatanodeInfoWithStorag</code>, It seems like there is some issue with datanode.

If you look into the running services in the cluster, and check if all datanodes and daemons are running fine; things may go in track.

Issues could be:

<ol>
<li>Issue in datanode. Restart cluster daemons.</li>
<li>Heart beat between datanodes and namenode: Network Issues or permission access issues.</li>
<li>datanode's memory issue.</li>
<li>Datanode busy or unresponsive</li>
</ol>

If you look at the documentation of <a href="https://docs.oracle.com/javase/7/docs/api/java/lang/Throwable.html#addSuppressed(java.lang.Throwable)" rel="nofollow noreferrer">Throwable</a> you'll find some useful information about the <code>addSuppressed</code> method. Specifically, if you have an <code>exception e</code>, and you do <code>e.addSuppressed(e)</code>, then a new IllegalArgumentException exception would be generated. This exception would show as
<pre><code>java.lang.IllegalArgumentException: Self-suppression not permitted
</code></pre>
And of course, nothing about the original exception <code>e</code> would be shown.
Here are the errors that can be thrown when calling <code>addSuppressed</code>:
<blockquote>
Throws:
IllegalArgumentException - if exception is this throwable; a throwable cannot suppress itself.
NullPointerException - if exception is null
</blockquote>

When the spark was writing a large file to HDFS using saveAsTextFile, I got an error: <code>java.lang.IllegalArgumentException: Self-suppression not permitted at java.lang.Throwable.addSuppressed(Throwable.java:1043)
Caused by: java.io.IOException: All datanodes DatanodeInfoWithStorage
</code>

I've searched for a solution to this, but I've not found the right solution and I don't know why.

What is causing these errors, and how can I fix them?

What is the main cause of "self-suppression not permitted" in Spark?
