I'd like to merge SOLR-17180: Deprecate snapshotscli.sh in favour of bin/solr sub commands next week.
https://github.com/apache/solr/pull/2381 I've emailed the user list for additional eyes, but with no luck. https://lists.apache.org/thread/l6wyx5yvw8nqxlm1wyw45hld34blvyov I'm thinking this will land in main, but not get backported to 9x since the HDFS stuff hasn't received much testing/review.
