Getting error right after installing quartz and river-web

[iouri-kostine]

ES version 1.2.1 river-web version 1.2.0 Followed docs to install quartz and river-web. Started ES and got this error:

{1.2.1}: Initialization Failed ...
1) InvocationTargetRuntimeException[[ESSR0043]The target which org.apache.http.impl.conn.PoolingHttpClientConnectionManager invoked is illegal, because java.lang.NoSuchFieldError: INSTANCE]
    NoSuchFieldError[INSTANCE]

Any ideas what might be causing it?

Could you check if your ES has other httpclient jar file?

$ ls [ES_HOME]/plugins/*/httpclient*

It does. I have one other, version 4.2 inside of AWS plugin.

Copied newer version into the AWS plugin, ES is starting without an error. Workaround but at least I can continue with testing. Thanks
