Anoop Sam John commented on HBASE-24632:
----------------------------------------

bq.Only concern is the compaction after region open, which impact MTTR due to 
heavy IO in large cluster with many outstanding WALs
I see. This compaction adding more IO pressure on storage which is already 
under heavy usage. !!! Good point. That also to consider. 

> Enable procedure-based log splitting as default in hbase3

> Means changing this value in HConstants to false:
>    public static final boolean DEFAULT_HBASE_SPLIT_COORDINATED_BY_ZK = true;
> Should probably also deprecate the current zk distributed split too so we can 
> clear out those classes to.
