							 The hdfs-site.xml property dfs.namenode.num.extra.edits.retained defaults to a value of 1000000 (1 million)   Reducing this value will lower the number of edit logs retained after a checkpoint in complete.

							 Have you tried to retrieve the logs using the YARN CLI?  yarn logs -applicationId <id of the application>   This will stream back the aggregated log to the screen ... if you have access in HDFS to see the log files. You will see a message about aggregation not being enabled if you lack permissions to see the log files. In that case, modify the command to use the application owner.  yarn logs -appOwner <user id> -applicationId <id of the application>

							 In an HA environment, I see a fairly current fsimage file in the Namenode directory.  But I also see edit files for the last 20+ days even though the checkpoint frequency is 6 hours/1M transactions.

							 There is an odd environment variable used for the HBase configuration directory.  Try setting HBASE_CONF_PATH=/etc/hbase/conf in your shell session and see if the timeout value gets picked up.

							 The incorrect status was caused by the contents of the zookeeper_server.pid file being out of sync with the running zookeeper process. Updating the file with the proper PID allowed the correct Zookeeper status to be displayed in Ambari.
