Commit 1647726 from [~thelabdude] in branch 'dev/trunk'
[ https://svn.apache.org/r1647726 ]
SOLR-6867: SolrCLI should check for existence before creating a new
core/collection, more user-friendly error reporting (no stack trace), and the
ability to pass a directory when using bin/solr to create a core or collection
> bin/solr -e foo should use collection/cores api to check if collection/core
> exists before trying to create it

> currently if you run an example command and the core/collection being created
> already exists you get an error message in the console, ut then the example
> keeps working (see below).
> I think it would be better if the script used the cores api (or collection
> api in the 'cloud' example) to check if the collection already existed, and
> if so just output a note about it, something like...
> {noformat}
> Core API indicates a core named 'techproducts' already exists...
> http://localhost:8983/solr/admin/cores?action=status&core=techproducts
> To remove this core, use the following command...
> bin/solr ...etc...
> And then you can recreate it with...
> bin/solr ...etc...
> {noformat}
