---------------------------------

             Summary: Use a time based expiration cache for one off hdfs FileSystem instances.
                 Key: SOLR-7391
                 URL: https://issues.apache.org/jira/browse/SOLR-7391
             Project: Solr
          Issue Type: Improvement
          Components: s, hdfs
            Reporter: Mark Miller
            Assignee: Mark Miller


Most FileSystem clients are tied to a SolrCore and long lived, but in some cases where we don't have SolrCore context we create a short lived hdfs client object.

Because these instances can be created via user generated actions, we don't want to be able to create too many of them - they have overhead that does not make them great candidates for being spun up for a single call.
