public int getSyncWaitTimeout()
```
    Description copied from interface: Admin
    
    Return the blocking wait time for an asynchronous operation. Can be configured by hbase.client.sync.wait.timeout.msec.
    For several operations, such as createTable, deleteTable, etc, the rpc call will finish right after we schedule a procedure at master side, so the timeout will not be controlled by the above Admin.getOperationTimeout(). And timeout value here tells you how much time we will wait until the procedure at master side is finished.
    In general, you can consider that the implementation for XXXX method is just a XXXXAsync().get(getSyncWaitTimeout(), TimeUnit.MILLISECONDS).

```
public void snapshot(String snapshotName,
                     TableName tableName)
```
    Description copied from interface: Admin
    
    Take a snapshot for the given table. If the table is enabled, a FLUSH-type snapshot will be taken. If the table is disabled, an offline snapshot is taken. 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[]).
    
    Specified by:
    
    snapshot in interface Admin
    
    Parameters:
    
    snapshotName - name of the snapshot to be created
    
    tableName - name of the table for which snapshot is created
  - snapshot
```
public void snapshot(byte[] snapshotName,
                     TableName tableName)
```
    Description copied from interface: Admin
    
    Create a timestamp consistent snapshot for the given table. Snapshots are considered unique based on the name of the snapshot. Attempts to take a snapshot with the same name (even 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.
    
    Specified by:
    
    snapshot in interface Admin
    
    Parameters:
    
    snapshotName - name of the snapshot to be created
    
    tableName - name of the table for which snapshot is created
  - snapshot
```
public void snapshot(String snapshotName,
                     TableName tableName,
                     SnapshotType type)
```
    Description copied from interface: Admin
    
    Create typed snapshot of the table. 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[]).
    
    Specified by:
    
    snapshot in interface Admin
    
    Parameters:
    
    snapshotName - name to give the snapshot on the filesystem. Must be unique from all other snapshots stored on the cluster
    
    tableName - name of the table to snapshot
    
    type - type of snapshot to take
  - snapshot
```
public void snapshot(SnapshotDescription snapshot)
```
    Description copied from interface: Admin
    
    Take a snapshot and wait for the server to complete that snapshot (blocking). Snapshots are considered unique based on the name of the snapshot. Snapshots are taken sequentially even when requested concurrently, across all tables. 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 Admin.snapshot(String, org.apache.hadoop.hbase.TableName) or Admin.snapshot(byte[], org.apache.hadoop.hbase.TableName) unless you are sure about the type of snapshot that you want to take.
    
    Specified by:
    
    snapshot in interface Admin
    
    Parameters:
    
    snapshot - snapshot to take
  - snapshotAsync
```
public Future<Void> snapshotAsync(SnapshotDescription snapshot)
```
    Description copied from interface: Admin
    
    Take a snapshot without waiting for the server to complete that snapshot (asynchronous) Only a single snapshot should be taken at a time, or results may be undefined.
    
    Specified by:
    
    snapshotAsync in interface Admin
    
    Parameters:
    
    snapshot - snapshot to take
  - isSnapshotFinished
```
public boolean isSnapshotFinished(SnapshotDescription snapshot)
```
    Description copied from interface: Admin
    Check the current state of the passed snapshot. There are three possible states:
    1. running - returns false
    2. finished - returns true
    3. 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 Admin
    
    Parameters:
    
    snapshot - description of the snapshot to check
