While manually scheduling major compaction, should it be scheduled for Phoenix system tables too?

[#1]

I've to disable automatic major compaction in HBase by setting hbase.hregion.majorcompaction to 0 and have to schedule it manually for all tables in HBase using a cron job.

There are many HBase system tables like System.Catalog etc. Do I need to schedule it manually for these system tables too?

Usually SYSTEM tables are not large enough to qualify for major compaction and we can exclude it while doing compaction. You can have a look at the size of these tables in HDFS.
