Subject Re: SolrCloud 7.2.1 - UnsupportedOperationException thrown after query on specific environments
Date Fri, 02 Mar 2018 03:01:27 GMT
bq: These errors only occur when we run this job from our remote job server

Maybe your remote job server is using a different set of jars than
your local one? How does the remote job server work?

No log snippets came through BTW, so I'm guessing a bit. The Apache
mail server is quite aggressive about stripping stuff....

Best,
Erick
