Michael Stack commented on HBASE-25099:
---------------------------------------
Sure.
There exists a mechanism currently for setting replica count on hbase:meta that
comes from region replicas. In HConstants are the following defines:
{color:#000080}public static final {color}String
{color:#660e7a}META_REPLICAS_NUM {color}=
{color:#008000}"hbase.meta.replica.count"{color};
{color:#000080}public static final int
{color}{color:#660e7a}DEFAULT_META_REPLICA_NUM {color}= {color:#0000ff}1{color};
Could make it so you do replicas on meta same way you do it on user-space table.

> Project: HBase
> Issue Type: Improvement
> Components: meta, read replicas
> Reporter: Duo Zhang
> Priority: Major
>
> As now we support altering meta table, it will be better to also deal with
> changing meta replica number using altering meta, i.e, we could unify the
> logic in MasterMetaBootstrap to ModifyTableProcedure, and another benefit is
> that we do not need to restart master when changing the replica number for
> meta.
