I didn’t want to install Solr just so Jenkins could use one script. The Python is standalone.
I was using the zkCli tools, which were just not all that well documented. I never could find a description of exactly which files were copied where. The solr.xml directory structure had <core>/conf/<files>, but it wasn’t clear what was expected for the bootstrap commands. Fetching the zk information from a running cluster is also less error prone. Don’t need to keep Jenkins configured the same as the cluster. Oh, I skipped a step, the Python script also uploads solr.xml. wunder Walter Underwood wun...@wunderwood.org http://observer.wunderwood.org/ (my blog) > On Apr 18, 2018, at 9:14 AM, Erick Erickson <erickerick...@gmail.com> wrote: > > There are some perhaps easier ways to manipulate ZK in the "bin/solr" > script if you haven't seen it > > bin/solr zk -help > > Best, > Erick > > On Wed, Apr 18, 2018 at 8:30 AM, Arturas Mazeika <maze...@gmail.com> wrote: >> Hi Walter, >> >> Thanks for the message.
