LogRecoveredEditsOutputSink

public LogRecoveredEditsOutputSink(WALSplitter walSplitter,
                                   WALSplitter.PipelineController controller,
                                   EntryBuffers entryBuffers,
                                   int numWriters)

方法详细资料

finishWritingAndClose

public List<org.apache.hadoop.fs.Path> finishWritingAndClose()
                                                      throws IOException

指定者:

finishWritingAndClose 在类中 OutputSink

返回:

null if failed to report progress

抛出:

IOException

append

public void append(WALSplitter.RegionEntryBuffer buffer)
            throws IOException

指定者:

append 在类中 OutputSink

参数:

buffer - A WAL Edit Entry

抛出:

IOException

keepRegionEvent

public boolean keepRegionEvent(WAL.Entry entry)

从类复制的说明: OutputSink

Some WALEdit's contain only KV's for account on what happened to a region. Not all sinks will want to get all of those edits.

指定者:

keepRegionEvent 在类中 OutputSink

返回:

Return true if this sink wants to accept this region-level WALEdit.

getOutputCounts

public Map<byte[],Long> getOutputCounts()

指定者:

getOutputCounts 在类中 OutputSink

返回:

a map from encoded region ID to the number of edits written out for that region.

getNumberOfRecoveredRegions

public int getNumberOfRecoveredRegions()

指定者:

getNumberOfRecoveredRegions 在类中 OutputSink

返回:

number of regions we've recovered
