Mark Miller commented on SOLR-9284:
-----------------------------------
* 1. In BlockDirectoryCache, the map between name and integer is changed to
use Caffeine cache without setting up removal listener...
It never had a removal listener. This is the names map mentioned above. We
can't easily remove names, that is the point of just setting an upper size on
it.
* 2. There are a few occurrences of System.out.println() in
BlockDirectoryCache. It's better to use log.
This is just debug statements for development, no need to log, they just need
to be removed before commit.
> The HDFS BlockDirectoryCache should not let it's keysToRelease or names maps
> grow indefinitely.
