Subject Elasticsearch Indexing Bolt NullPointerException
Date Tue, 07 Jun 2016 15:09:45 GMT
Hello,

We’re currently testing all of our parsers on our QA environment and as we added more parsers,
the enrichment topology started slowing down dramatically. Namely, the indexingBolt had a
process latency of 12ms and now it’s 200ms, (Execute latency went from 2 to 25).

Upon further inspection, the indexing bolt has lots and lots of NullPointerExceptions. The
logs are less than helpful, as they look like this:

Has anyone seen this kind of error before and know what is causing it?

Thanks,
