Java.lang.ClassNotFoundException: org.elasticsearch.transport.RemoteTransportException


(Earle Nietzel) #1

Using elasticsearch embedded in tomcat 7 where we have custom classloader
that shares spring application beans with many webapps. The API's to these
implementations are in shared but the implementations are in a separate
classloader "ComponentLoader". Our search implementation is loaded from
ComponentLoader where elasticsearch has been promoted as our default search
engine.

Everything works fine on a single node but when in a cluster seeing the
following ClassNotFoundException issue when shards are trying to update on
other nodes.

I thought this might have been related

doesn't seem to be the case.

My next idea is to look at why
org.elasticsearch.common.io.ThrowableObjectInputStream.loadClass is
invoking WebappClassLoader instead of our custom ComponentLoader and coerce
it to use ours.

But I wanted to get some opinions on this strategy as I am new to
elasticsearch :wink:

The cluster wants to transport an exception to your web app container, and
the web app does not have access to elasticsearch jar.

You should have a look at the ES server logs, if there are any exceptions,
to find the real problem.

Then, after fixing the real problem, you should try to configure your web
app so the elasticsearch jar is in the classpath.

To your question about WebAppClassLoader: ES uses the thread context class
loader
https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/common/Classes.java#L56

Also, do you use any ES plugins? If plugins throw exceptions, they must
also be available in the web app.

Hi Jörg,

I was able to resolve this by moving elasticsearch and its dependencies
into tomcats shared/lib. Since Tomcats shared classloader is always in the
chain of classloaders to search the ClassNotFoundException's are no more.

Though there shouldn't have been any reason for elasticsearch to not work
in the custom ComponentLoader, this did work in the 0.90.x series. We only
experienced these classloader issues when ES was sending shard data to
another node in the cluster which lead me to beleive that the Netty
Transport for some reason was not using the classloader from the original
ImmutableSettings.

Its my guess that the ImmutableSettings object was not present which is why
it chose to use use the Classes.getDefaultClassLoader().

Thanks for your direction was very helpful in figuring this out,
Earle
