> Now, there is no limit for users who can create table under 'hbase' NameSpace. I think it has some risk.
> Because we use {{TableName.systemTable}} to decide whether this table is System or not.
> But as code, {{TableName.systemTable}} will be true, if NS equals "hbase'
> {code}
> if (Bytes.equals(NamespaceDescriptor.SYSTEM_NAMESPACE_NAME, namespace)) {
> this.namespace = NamespaceDescriptor.SYSTEM_NAMESPACE_NAME;
> this.namespaceAsString = NamespaceDescriptor.SYSTEM_NAMESPACE_NAME_STR;
> this.systemTable = true;
> }
> {code}
>
> And we treat system table and normal table differently.
> For example, https://issues.apache.org/jira/browse/HBASE-14257 will flush fast if table belong to system table.
