Hi everyone,

After fixing the error with log4j as recommended [here](https://discuss.elastic.co/t/issue-with-elastic-search-5-0-0-java-lang-classnotfoundexception-org-apache-logging-log4j-core-async-daemonthreadfactory/64345?u=quent).

I have now the following error:

```
Exception in thread "main" java.lang.NoSuchMethodError: io.netty.buffer.CompositeByteBuf.addComponents(ZLjava/lang/Iterable;)Lio/netty/buffer/CompositeByteBuf;

Hey @wxx520,  
This problem is caused by concurrent versions of Netty being used by different dependencies in your project.  
Basically, ES 5 Transport API required Netty 4. And Dependency X, still use Netty 3. This can cause this problem.

What I tried:

1. Add Netty 4 as dependecy in my project -\> Didn't work.
2. Create an independant project for my use of ES 5 Transport Client -\> It worked.

My use of the Transport client was only to create an index and the mapping. Documents are stored with the elasticsearch spark connector.

I would advise you to try 1. And then if it does not work try 2.

Hi,@Quent!  
Thank you very much for your advice!The problem I encountered really was caused by a Netty version conflict.And I have solved it by trying 1.  
My use of the Transport client is to play a role similar to the postman by java code .  
And I has completed bulk index and update by Transport client. Next step is to the mapping.If i  
My English is not very good.Nonetheless be glad to talk to you!
