> Project: HBase
> Issue Type: Improvement
> Components: Client, Zookeeper
> Affects Versions: 2.0.0
> Reporter: Mikhail Antonov
> Assignee: Mikhail Antonov
> Fix For: 2.0.0

> After committing patch for HBASE-4495, there's an further improvement which
> can be made (discussed originally on review board to that jira).
> We have MetaTableAccessor and MetaTableLocator classes. First one is used to
> access information stored in hbase:meta table. Second one is used to deal
> with ZooKeeper state to find out region server hosting hbase:meta, wait for
> it to become available and so on.
> MetaTableAccessor, in turn, should only operate on the meta table content, so
> shouldn't need ZK. The only reason why MetaTableAccessor is using ZK - when
> callers request assignment information, they can request location of meta
> table itself, which we can't read from meta, so in that case
> MetaTableAccessor relays the call to MetaTableLocator. May be the solution
> here is to declare that clients of MetaTableAccessor shall not use it to work
> with meta table itself (not it's content).
