Jellyfrog created SOLR-7526:
-------------------------------
Summary: When replacing index contents and reloading the core,
index is deleted
Key: SOLR-7526
URL: https://issues.apache.org/jira/browse/SOLR-7526
Project: Solr
Issue Type: Bug
Affects Versions: 5.1
Environment: Ubuntu 14.04
Reporter: Jellyfrog
I want to replace the index with another index, so I replace the files and do a
RELOAD, and the index disappears.
Steps to reproduce:
1. Create an empty core (no index/tlog)
2. Add it to Solr and let it autocreate the index-folders
{code}
$ find data/
data/
data/index
data/index/write.lock
data/index/segments_1
data/tlog
{code}
3. Replace the index with another
{code}
$ find data/
data
data/index
data/index/write.lock

4. Reload the core
{code}
$ curl "http://solr.local:8983/solr/admin/cores?action=RELOAD&core=core0";
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int
name="QTime">420</int></lst>
</response>
{code}
5. The new index is now gone
{code}
# find data/
data/
data/index
data/index/write.lock
data/index/segments_1
data/tlog
data/tlog/tlog.0000000000000001016
