Solr connection refused

slavo — Fri, 16 Sep 2022 09:55:35 GMT

Hi,

I'm trying to reindex some PDF and Word documents using MapReduceIndexerTool but getting just "connection refused" (see complete error message below)

This used to work earlier, so the Morphline and the collection are fine. Using CDH 5.0.0 Quickstart VM. Used dry-run and verbose options, but no additional info available. SolrCloud logs do not show anything suspicious either. Maybe zookeeper got stuck?

Any ideas?

Regards,

Slavo

Find the "solution" myself. YARN was down, had to restart it.
