* queueId. Each queue must have the following two columns:

* COL_QUEUE_OWNER: tracks which server is currently responsible for tracking the queue
|
|

* COL_QUEUE_OWNER_HISTORY: a "|" delimited list of the previous server's that have owned this

* queue. The most recent previous owner is the leftmost entry.
|
|
||||||
* They will also have columns mapping [WAL filename : offset]
|
|
||||||
* The most flexible method of interacting with the Replication Table is by calling
|

* getOrBlockOnReplicationTable() which will return a new copy of the Replication Table. It is up

|
||||||
* to the caller to close the returned table.

* ZK based replication queue storage.
|
||||||
|
* <p>
|
||||||
|
* The base znode for each regionserver is the regionserver name. For example:
|
||||||
|
*
|
||||||
|
* <pre>
|
||||||
|
* /hbase/replication/rs/hostname.example.org,6020,1234
|
||||||
|
* </pre>
|
||||||
|
*
|
||||||
|
* Within this znode, the region server maintains a set of WAL replication queues. These queues are
|
||||||
|
* represented by child znodes named using there give queue id. For example:
|
||||||
|
*
|
||||||
|
* <pre>
|
||||||
|
* /hbase/replication/rs/hostname.example.org,6020,1234/1
|
||||||
|
* /hbase/replication/rs/hostname.example.org,6020,1234/2
|
||||||
|
* </pre>
|
||||||
|
*
|
||||||
|
* Each queue has one child znode for every WAL that still needs to be replicated. The value of
|
||||||
|
* these WAL child znodes is the latest position that has been replicated. This position is updated
|
||||||
|
* every time a WAL entry is replicated. For example:
|
||||||
|
*
|
||||||
|
* <pre>
|
||||||
|
* /hbase/replication/rs/hostname.example.org,6020,1234/1/23522342.23422 [VALUE: 254]
