Mark Miller created SOLR-8258:
---------------------------------

             Summary: Change default hdfs tlog replication factor from 1 to 3 in 6x.
                 Key: SOLR-8258
                 URL: https://issues.apache.org/jira/browse/SOLR-8258
             Project: Solr
          Issue Type: Improvement
          Components: hdfs
            Reporter: Mark Miller
            Assignee: Mark Miller


Some HDFS features, such as lease recovery, really don't like a replication factor of 1. We have found that it is best to default this to 3.
