Hello, when running the crawler with multiple threads, I get the following error:

When I run with 1 thread it completes successfully:

In both cases, I started clean by removing the index in ES, removing the committer-queue, and workdir files (just to be sure nothing was left over from previous runs). Here is my environment:

I am not sure what is causing this issue. Please advise Thanks in advance

I have reproduced the error by first committing all of my documents using the filesystem committer. Then I ran the ES committer on the queue directory (created from the FS committer). It gives the same error as above but I don't know how to trace where the problem is. I made sure I have the latest of everything. Here is the log of error:

Again, the above was for running just the committer with the below command and xml:

collector-fs.bat -a start -c c:\Elastic\ingest\norconex\config\elastic.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>

  <crawlers>
    <crawler id="WM Search Commit">

      <committer class="com.norconex.committer.elasticsearch.ElasticsearchCommitter">
        <nodes>http://localhost:9200</nodes>
        <indexName>wmsearch</indexName>

        <queueSize>9999999</queueSize>
        <commitBatchSize>100</commitBatchSize>
      </committer>

    </crawler>
  </crawlers>

</fscollector>

This was caused by a conflict between two library dependencies. It was fixed as part of #16. Please confirm.

[essiembre]

Once you installed the new committer snapshot, it is possible the faulty jar is still there within the filesystem collector. A new release of the Filesystem collector should be made soon, but in the meantime, delete this file if you still have the issue after the committer install: json-20160810.jar.

[essiembre]

FYI, a new snapshot of the Filesystem Collector was just released without that conflicting dependency.
