public abstract class CheckpointMetadataOutputStream extends FSDataOutputStream

|Constructor and Description|
|Modifier and Type||Method and Description|
This method should close the stream, if has not been closed before.
Closes the stream after all metadata was written and finalizes the checkpoint location.
public abstract CompletedCheckpointStorageLocation closeAndFinalizeCheckpoint() throws IOException
IOException- Thrown, if the stream cannot be closed or the finalization fails.
public abstract void close() throws IOException
The above implies that this method is intended to be the "unsuccessful close", such as
when cancelling the stream writing, or when an exception occurs. Closing the stream for the
successful case must go through
