saintstack opened a new pull request #2413:
URL: https://github.com/apache/hbase/pull/2413
ReplicationSource filters in hbase:meta WALs and filters out
user-space WALs. Allows all edits from meta WALs through.
Does not persist replication state to backing store; it is
not needed for in-cluster region replicas (but this patch
only adds this improvment on async WAL region replicas
for hbase:metai table).
Made it explicit that a ReplicationSource feeds from a
WALProvider.
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
Fix logging; don't log we've flushed when we haven't.
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Pass WALFactory instead of WALProvider... WALFactory has
user-space and meta WALProviders. Pass so replication can
get access to meta WALs. Add spinning up a thread to run
flush of primary Region if it hbase:meta table.
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ReplicationService.java
Take a WALFactory rather than a WALProvider.
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/AssignRegionHandler.java
If we are opening hbase:meta Region and hbase:meta region read replicas
are enabled, then add hbase:meta WALs as a repliation source.
Bug fix... We were using a CLOSE executor when opening.
hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/handler/UnassignRegionHandler.java
If closing hbase:meta, then remove replication source if in place.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/HBaseMetaNoQueueStoreReplicationSource.java
Special-case ReplicationSource used by hbase:meta read replicas.
Configured to suit reading hbase:meta WALs.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/Replication.java
Pass walFactory instead of walProvider. Move adding of listener
elsewhere to accomodate lazy instantiation of hbase:meta
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSource.java
Take walProvider on construction and remove the length function from init.
Clean up some namings; queueId vs peerId vs walGroupId.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSourceFactory.java
Add being able to create an hbase:meta region read replica
ReplicationSource.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSourceInterface.java
Adds a getWALProvider.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/ReplicationSourceManager.java
Add key for the hbase:meta region read replica replication source.
Take WALFactory rather than WALProvider. It has pointers to all
hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Expose useful util.
hbase-server/src/main/java/org/apache/hadoop/hbase/replication/regionserver/RegionReplicaReplicationEndpoint.java
Make it work for the case of lazy onlining of hbase:meta replicas.
