[Parameter] hbase.hregion.majorcompaction [Default] 7 days (604800000 milliseconds) [Description] 
Time between major compactions, expressed in milliseconds. Set to 0 to disable time-based automatic major compactions. User-requested and size-based major compactions will still run. This value is multiplied by hbase.hregion.majorcompaction.jitter to cause compaction to start at a somewhat-random time during a given window of time.
