-------------------------------------------
Summary: create_core command gives confusing messages if broken
config is given, fixed, given again
Key: SOLR-8246
URL: https://issues.apache.org/jira/browse/SOLR-8246
Project: Solr
Issue Type: Improvement
Components: scripts and tools
Affects Versions: 5.3.1
Reporter: Alexandre Rafalovitch
Priority: Minor
If the config used to create a core, the command complains and aborts:
Example:
{code}
$ bin/solr create_core -c minicore -d ../miniconf/
Creating new core 'minicore' using command:
http://localhost:8983/solr/admin/cores?action=CREATE&name=minicore&instanceDir=minicore
ERROR: Error CREATEing SolrCore 'minicore': Unable to create core [minicore]
Caused by: The element type "dynamicField" must be terminated by the matching
end-tag "</dynamicField>".
{code}
However, after fixing the problem, trying to re-run the command gives the same
error, causing all sorts of confusion.
What actually happened is that config has been copied to the destination
directory and then when the command is run the second time, it does not recopy
fresh - and fixed - files, but just reuses the previously copied - broken -
ones.
The workaround is to manually delete created destination directory and rerun
the command. But it is far from obvious.
The fix would be either undoing the copy - a delete. The minimal fix would be a
log statement that the directory was copied (which would help example logs
too). And perhaps an extra message when the create command failed that files
were copied and may need to be manually deleted.
