Class Summary | |
---|---|
Compressor | A set of static functions for running our custom WAL compression/decompression. |
HLog.Entry | Utility class that lets us keep track of the edit with it's key. |
HLogFactory | |
HLogKey | A Key for an entry in the change log. |
HLogPrettyPrinter | HLogPrettyPrinter prints the contents of a given HLog with a variety of options affecting formatting and extent of content. |
HLogSplitter | This class is responsible for splitting up a bunch of regionserver commit log files that are no longer being written to, into new files, one per region for region to replay on startup. |
HLogSplitter.MutationReplay | A struct used by getMutationsFromWALEntry |
HLogUtil | |
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 HLog's MetricsWAL into the metrics subsystem. |
ProtobufLogReader | A Protobuf based WAL has the following structure: |
ProtobufLogWriter | Writer for protobuf-based WAL. |
ReaderBase | |
SecureProtobufLogReader | |
SecureProtobufLogWriter | |
SecureWALCellCodec | A WALCellCodec that encrypts the WALedits. |
SequenceFileLogReader | |
WALCellCodec | Compression in this class is lifted off Compressor/KeyValueCompression. |
WALCoprocessorHost | Implements the coprocessor environment and runtime support for coprocessors
loaded within a FSHLog . |
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. |
WriterBase | Context used by our wal dictionary compressor. |
