org.apache.hadoop.hbase.client.AsyncHBaseAdmin

All Implemented Interfaces:: AsyncAdmin

@Private class AsyncHBaseAdmin extends Object implements AsyncAdmin

Just a wrapper of RawAsyncHBaseAdmin. The difference is that users need to provide a thread pool when constructing this class, and the callback methods registered to the returned CompletableFuture will be executed in this thread pool. So usually it is safe for users to do anything they want in the callbacks without breaking the rpc framework.

Since:

2.0.0

- snapshot
  
  public CompletableFuture<Void> snapshot(SnapshotDescription snapshot)
  
  Description copied from interface: AsyncAdmin
  
  Take a snapshot and wait for the server to complete that snapshot asynchronously. Snapshots are taken sequentially even when requested concurrently, across all tables. Snapshots are considered unique based on the name of the snapshot. Attempts to take a snapshot with the same name (even a different type or with different parameters) will fail with a SnapshotCreationException indicating the duplicate naming. Snapshot names follow the same naming constraints as tables in HBase. See TableName.isLegalFullyQualifiedTableName(byte[]). You should probably use AsyncAdmin.snapshot(String, org.apache.hadoop.hbase.TableName) unless you are sure about the type of snapshot that you want to take.
  
  Specified by:
  
  snapshot in interface AsyncAdmin
  
  Parameters:
  
  snapshot - snapshot to take
- isSnapshotFinished
  
  public CompletableFuture<Boolean> isSnapshotFinished(SnapshotDescription snapshot)
  
  Description copied from interface: AsyncAdmin
  Check the current state of the passed snapshot. There are three possible states:
  
  running - returns false
  
  finished - returns true
  
  finished with error - throws the exception that caused the snapshot to fail
  
  The cluster only knows about the most recent snapshot. Therefore, if another snapshot has been run/started since the snapshot you are checking, you will receive an UnknownSnapshotException.
  Specified by:
  
  isSnapshotFinished in interface AsyncAdmin
  
  Parameters:
  
  snapshot - description of the snapshot to check
  
  Returns:
  
  true if the snapshot is completed, false if the snapshot is still running
- restoreSnapshot
  
  public CompletableFuture<Void> restoreSnapshot(String snapshotName)
  
  Description copied from interface: AsyncAdmin
  
  Restore the specified snapshot on the original table. (The table must be disabled) If the "hbase.snapshot.restore.take.failsafe.snapshot" configuration property is set to true, a snapshot of the current table is taken before executing the restore operation. In case of restore failure, the failsafe snapshot will be restored. If the restore completes without problem the failsafe snapshot is deleted.
  
  Specified by:
  
  restoreSnapshot in interface AsyncAdmin
  
  Parameters:
  
  snapshotName - name of the snapshot to restore
- restoreSnapshot
  
  public CompletableFuture<Void> restoreSnapshot(String snapshotName, boolean takeFailSafeSnapshot, boolean restoreAcl)
  
  Description copied from interface: AsyncAdmin
  
  Restore the specified snapshot on the original table. (The table must be disabled) If 'takeFailSafeSnapshot' is set to true, a snapshot of the current table is taken before executing the restore operation. In case of restore failure, the failsafe snapshot will be restored. If the restore completes without problem the failsafe snapshot is deleted. The failsafe snapshot name is configurable by using the property "hbase.snapshot.restore.failsafe.name".
  
  Specified by:
  
  restoreSnapshot in interface AsyncAdmin

- getConfiguredNamespacesAndTablesInRSGroup
  
  public CompletableFuture<Pair<List<String>,List<TableName>>> getConfiguredNamespacesAndTablesInRSGroup(String groupName)
  
  Description copied from interface: AsyncAdmin
  
  Get the namespaces and tables which have this RegionServer group in descriptor.
  The difference between this method and AsyncAdmin.listTablesInRSGroup(String) is that, this method will not include the table which is actually in this RegionServr group but without the RegionServer group configuration in its TableDescriptor. For example, we have a group 'A', and we make namespace 'nsA' in this group, then all the tables under this namespace will in the group 'A', but this method will not return these tables but only the namespace 'nsA', while the AsyncAdmin.listTablesInRSGroup(String) will return all these tables.

  groupName - the group name
