I can think of a corollary core action I'd like to see – the ability on a core
RELOAD to entirely delete the index from a core and replace it with a fresh
empty index that will start building at segment _0. I would do this to my
build core before using it, and later after swapping it with the live core
and ensuring it's good, to free up disk space.
{quote}
Shawn, that is not a use-case for RELOAD. The idea behind it is to reload an
existing core's index with updated configuration changes and swap it with the
existing core without causing downtime. It seems like your use-case is handled
well with the stock CREATE, SWAP and UNLOAD+deleteIndex?

Project: Solr
Issue Type: Improvement
Components: multicore
Reporter: Shalin Shekhar Mangar

Priority: Minor
Fix For: 3.3, 4.0
Attachments: SOLR-2610-branch3x.patch, SOLR-2610.patch
Right now, one can unload a Solr Core but the index files are left behind and
consume disk space. We should have an option to delete the index when
unloading a core.

I didn't and I'm sorry about that. I was just trying to tell you my perspective. These are small pieces that need to be fixed before tackling larger problems in SolrCloud and this one seemed generally useful and simple enough by itself that I opened the issue without giving the bigger picture. Some of the other pieces are captured in SOLR-2595 bq. Why are you deleting cores only to add them back again with the same config? Hopefully SOLR-2595 will give you a better idea of what I was thinking. The use-case is to split and migrate pieces of an index and this issue will help in deleting the leftover temporary cores. bq. Do you really think it's inconsistent to actually be able to delete something? The inconsistency is to be able to delete a configuration file when there is no way to add it back but I'm not against the feature in general. bq. Does it really seem like a weird use case to say, I want to delete a SolrCore I no longer have an interest in? Absolutely not. If you want that feature, that's fine. You don't need permissions to put up a patch and commit it :) bq. Looks like a few people have an interest in this issue, so I'm not sure why you rammed it in so quickly. The issue clearly talks about deleting index on unload and that's what it does. And I got a +1 from you and Jason on the topic of the issue (or at least, that's what I assumed). I waited a day to commit - would you like me to wait longer for future issues or leave a comment to that effect? If the patch is not what you intended, go ahead and reopen/extend the scope of the issue or open another issue.

Shawn, that is not a use-case for RELOAD. The idea behind it is to reload an existing core's index with updated configuration changes and swap it with the existing core without causing downtime. It seems like your use-case is handled well with the stock CREATE, SWAP and UNLOAD+deleteIndex? CREATE requires that the caller be aware of internal server filesystem structures. For the typical use of CREATE, this is not really a problem, but if what you're trying to do is unload a core, delete its index, and then immediately recreate it with the same config, it would be very nice to not have to specify (or even know) the solr.xml configuration bits. In this particular case, the person who writes the scripts is the same person who maintains the Solr infrastructure (me) ... but that might not always be the case. Currently the build scripts don't know anything about the internal structure other than core names, and I'd like to keep it that way. Adding an option like deleteIndex to RELOAD seemed a logical way to handle this, since currently (1.4.1) I have to completely restart Solr when I wipe out an index directory. If this is not a logical progression, I would argue that CoreAdmin needs an entirely new action. Either way, if it's deemed desirable, it needs its own Jira issue. I brought it up here because it's at least tangentially related.

The problem I think I encountered in my own version is left over file handles seemed to be preventing the deletion of all the files, many times some of them would be left over. Also I deleted the entire core directory, which is useful for manual testing (eg, to avoid the directory exists exception).
