I recently encountered a problem that the SOLR server went down while =
creating a collection. After SOLR returned to normal, I tried to create =
the collection again, but the server feedback:'collection already =
exists'.
I checked and found that the znode corresponding to the collection under =
the Zookeeper /collections path has been created, but the corresponding =
core was not found in solrHome.
After manually deleting the wrong znode under the /collections path, the =
collection can be successfully created. Is there any other more elegant =
recovery method besides this?=
