| Interface | Description |
|---|---|
| MetricsEditsReplaySource |
Interface of the source that will export metrics about log replay statistics when recovering a
region server in distributedLogReplay mode
|
| MetricsWALSource |
Interface of the source that will export metrics about the region server's WAL.
|
| WALActionsListener |
Get notification of WAL events.
|
| WALCellCodec.ByteStringCompressor | |
| WALCellCodec.ByteStringUncompressor |
| Class | Description |
|---|---|
| CompressionContext |
Context that holds the various dictionaries for compression in WAL.
|
| Compressor |
A set of static functions for running our custom WAL compression/decompression.
|
| FSHLog |
Implementation of
WAL to go against FileSystem; i.e. |
| HLogKey | Deprecated
use WALKey
|
| HLogPrettyPrinter | Deprecated
use the "hbase wal" command
|
| MetricsEditsReplaySourceImpl |
Hadoop1 implementation of MetricsMasterSource.
|
| MetricsWAL |
Class used to push numbers about the WAL into the metrics subsystem.
|
| MetricsWALEditsReplay |
Class used to push numbers about WAL edits replay into the metrics subsystem.
|
| MetricsWALSourceImpl |
Class that transitions metrics from MetricsWAL into the metrics subsystem.
|
| ProtobufLogReader |
A Protobuf based WAL has the following structure:
|
| ProtobufLogWriter |
Writer for protobuf-based WAL.
|
| ReaderBase | |
| ReplayHLogKey |
An HLogKey specific to WalEdits coming from replay.
|
| SecureProtobufLogReader | |
| SecureProtobufLogWriter | |
| SecureWALCellCodec |
A WALCellCodec that encrypts the WALedits.
|
| SequenceFileLogReader | |
| WALActionsListener.Base | |
| WALCellCodec |
Compression in this class is lifted off Compressor/KeyValueCompression.
|
| WALCellCodec.EnsureKvEncoder | |
| WALCoprocessorHost |
Implements the coprocessor environment and runtime support for coprocessors
loaded within a
WAL. |
| WALEdit |
WALEdit: Used in HBase's transaction log (WAL) to represent
the collection of edits (KeyValue objects) corresponding to a
single transaction.
|
| WALEditsReplaySink |
This class is responsible for replaying the edits coming from a failed region server.
|
| WALUtil |
Helper methods to ease Region Server integration with the write ahead log.
|
| WriterBase |
Context used by our wal dictionary compressor.
|
| Exception | Description |
|---|---|
| DamagedWALException |
Thrown when a failed append or sync on a WAL.
|
| FailedLogCloseException |
Thrown when we fail close of the write-ahead-log file.
|
| FailedSyncBeforeLogCloseException |
Thrown when we fail close of the write-ahead-log file.
