In the past, there was some proposal to improve this situation, eg. HBASE-13556 / HBASE-14190 (Assign system tables ahead of user region assignment) or HBASE-13557 (Special WAL handling for system tables) or HBASE-14623 (Implement dedicated WAL for system tables). > This JIRA proposes another way to solve this master initialization fail issue: namespace service is only used by a handful operations (eg. create table / namespace DDL / get namespace API / some RS group DDL). Only quota manager depends on it and quota management is off by default. Therefore, namespace service is not really needed for master to be functional. So we could start namespace service asynchronizely without blocking master startup. > -- This message was sent by Atlassian JIRA (v6.4.14#64029)
