@Shelton  Have you tested this property in your environment? Neither hbase.mob.file.expired nor hbase.mob.file.expired.period properties are present in hbase. A MOB HFile will be subject to archiving under any of the following conditions: Any MOB HFile older than the column family’s TTL Any MOB HFile older than a "too recent" threshold with no references to it from the regular hfiles for all regions in a column family MOB files are cleaned when MOB cleaner chore runs. This runs every 24 hours. Cleaner chore identifies the files whose TTL's are expired and removes them. TTL needs to be set on a table schema level. Default TTL is forever.    hbase.master.mob.cleaner.period Description The period that MobFileCleanerChore runs. The unit is second. The default value is one day. The MOB file name uses only the date part of the file creation time in it. We use this time for deciding TTL expiry of the files. So the removal of TTL expired files might be delayed. The max delay might be 24 hrs.
