    Added io.netty netty-all 4.1.17.Final io.netty netty 3.9.9.Final – Alchemist May 17 '18 at 10:16
  • NOT SURE WHAT IS CAUSING THIS ERROR ADDED PROPER JAR NO EFFECT. ANY HELP?? – Alchemist May 17 '18 at 10:16

    I have the same here, any solution. Incredible Spark dependency hell! – Joan Jun 21 '18 at 15:35

  • @Alchemist are you able to solve the issue because i am also facing the same. – Anubhav Jain Jan 01 '19 at 10:43
  • excluding netty-all & netty from spark dependency and adding it directly worked for me. I used the version netty-all - 4.1.17.Final netty - 3.9.9.Final It looks like a conflict in jars – dasrohith Oct 14 '20 at 12:41

This is because Hadoop binaries compiled with an older version and need us to just replace them. I haven't faced any issues with Hadoop by replacing them.

You need to replace netty-3.6.2.Final.jar and netty-all-4.0.23.Final.jar from path $HADOOP_HOME\share\hadoop with netty-all-4.1.17.Final.jar and netty-3.9.9.Final.jar.

  • really. I took those jars from spark installation and repleced those in hadoop and it worked.. – Vladimir Nabokov Aug 12 '19 at 11:09
  • Yes it worked. Strangely the [docs](https://netty.io/4.0/api/io/netty/buffer/PooledByteBufAllocator.html) show that it is part of 4.0 but seems like it only got included after 4.1. – TroubleShooter Jan 02 '20 at 16:10

This issue plagues due to mismatch of the version that Hadoop and Spark are compiled on for Netty. So you can follow this.

Similar Issue , solved by manually compiling the Spark by using specific version of Netty

And the other one as recommended by Suhas , by copying the content of SPARK_HOME/jars folder to the various lib folder or only the one in yarn inside HADOOP_HOME/share/hadoop solves the problem also. But it's a dirty fix. So maybe use latest version of both or manually compile them.

An older version of Netty was required by the aws-java-sdk. Deleting all the netty jars and removing the aws-java-sdk from the project solved the problem.

Issue has been resolved by adding the below netty jars in the dependencies,

   "io.netty" % "netty-all" % "4.1.68.Final"
   "io.netty" % "netty-buffer" % "4.1.68.Final"

And excluding all existing netty jars by adding excludeAll code.

 val excludeNettyBufferBinding = ExclusionRule(organization = "io.netty.buffer")
excludeAll(excludeNettyBufferBinding)
