      Description

      We only have the logs to the exception but not the metadata, so hard to reproduce. The log is:

      ERROR org.apache.hadoop.hdfs.server.namenode.FSEditLogLoader: Encountered exception on operation org.apache.hadoop.hdfs.server.namenode.FSEditLogOp$SetAclOp@7aad3f7d

      Let's use this jira to add more information to the exception, to hopefully help the next reoccurrence. (Have not failed again in the past week)
