David Smiley commented on SOLR-13392: ------------------------------------- bq. Do we have a test that tries to launch the exporter to avoid such bugs in the future? Apparently not! Docker is perfect for such a test, and we finally have Docker in our source tree but not yet Jenkins setup (whatever that may be). BTW I just filed SOLR-14915 to change the exporter to not depend on solr-core, which I think is crazy. > Unable to start prometheus-exporter in 7x branch > ------------------------------------------------ > > Key: SOLR-13392 > URL: https://issues.apache.org/jira/browse/SOLR-13392 > Project: Solr > Issue Type: Bug > Components: metrics > Affects Versions: 7.7.2 > Reporter: Karl Stoney > Assignee: Shalin Shekhar Mangar > Priority: Major > Fix For: 7.7.2, 8.1, master (9.0) > > Attachments: SOLR-13392.patch > > > Hi, > prometheus-exporter doesn't start in branch 7x on commit > 7dfe1c093b65f77407c2df4c2a1120a213aef166, it does work on > 26b498d0a9d25626a15e25b0cf97c8339114263a so something has changed between > those two commits causing this. > I am presuming it is > https://github.com/apache/lucene-solr/commit/e1eeafb5dc077976646b06f4cba4d77534963fa9#diff-3f7b27f0f087632739effa2aa508d77eR34 > Exception in thread "main" java.lang.NoClassDefFoundError: > org/apache/lucene/util/IOUtils > at > org.apache.solr.core.SolrResourceLoader.close(SolrResourceLoader.java:881) > at > org.apache.solr.prometheus.exporter.SolrExporter.loadMetricsConfiguration(SolrExporter.java:221) > at > org.apache.solr.prometheus.exporter.SolrExporter.main(SolrExporter.java:205) > Caused by: java.lang.ClassNotFoundException: org.apache.lucene.util.IOUtils > at java.net.URLClassLoader.findClass(URLClassLoader.java:382) > at java.lang.ClassLoader.loadClass(ClassLoader.java:424) > at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:349) > at java.lang.ClassLoader.loadClass(ClassLoader.java:357) > ... 3 more -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
