Can not send message to druid with tranquility spark on CDH5.9

Hi all,

When i use tranquility-spark_2.10 with verison 0.8.2 to send events to druid 0.9.2 on CHD5.9 in spark. i got the following error:

**java.lang.IllegalStateException: Failed to create merged beam: druid:overlord/path2**

The problem is, it can sends events to druid in my Intellij environment on local. But when i submit the application to spark cluster, it get the below error

Does someone meet the same issure?

Thanks



When i debug it, it is caused byjava.lang.NoSuchMethodError: org.jboss.netty.handler.codec.http.HttpMessage.headers()Lorg/jboss/netty/handler/codec/http/HttpHeaders;
