----------------------------------
Summary: zkcli: provide more granularity in config manipulation
Key: SOLR-8863
URL: https://issues.apache.org/jira/browse/SOLR-8863
Project: Solr
Issue Type: Improvement
Components: scripts and tools, SolrCloud
Affects Versions: 5.5
Reporter: Shawn Heisey
Priority: Minor
I was thinking about what somebody has to do if they want to replace a single
file in a specific SolrCloud configuration. This and other operations could be
easier with some tweaks to the zkcli program.
I'd like to have some options to do things like the following, and other
combinations not specifically stated here:
* Upload the file named solrconfig.xml to the 'foo' config.
* Upload the file named solrconfig.xml to the config used by the 'bar'
collection.
* Download the file named stopwords.txt from the config used by the 'bar'
collection.
* Rename schema.xml to managed-schema in the 'foo' config.
* Delete archaic_stopwords.txt from the config used by the 'bar' collection.
When a config is changed, it would be a good idea for the program to print out
a list of all collections affected by the change. I can imagine a
"-interactive" option that asks "are you sure" after printing the affected
collection list, and a "-dry-run" option to print out that information without
actually doing anything. An alternative to the interactive option -- have the
program prompt by default and implement a "-force" option to do it without
prompting.
I wonder whether it would be a good idea to include an option to reload all
affected collections after a change is made. The script uses WEB-INF/lib on
the classpath, so SolrJ should be available.
