Constructor Detail

• StripeMultiFileWriter.BoundaryMultiWriter

  public StripeMultiFileWriter.BoundaryMultiWriter(List<byte[]> targetBoundaries,
                                           byte[] majorRangeFrom,
                                           byte[] majorRangeTo)
                                            throws IOException

  Parameters:

  targetBoundaries - The boundaries on which writers/files are separated.

  majorRangeFrom - Major range is the range for which at least one file should be written (because all files are included in compaction). majorRangeFrom is the left boundary.

  majorRangeTo - The right boundary of majorRange (see majorRangeFrom).

  Throws:

  IOException

Method Detail

• append

  public void append(Cell cell)
              throws IOException

  Throws:

  IOException

• isCellAfterCurrentWriter

  private boolean isCellAfterCurrentWriter(Cell cell)

• commitWritersInternal

  protected void commitWritersInternal()
                                throws IOException

  Description copied from class: StripeMultiFileWriter
  Subclasses override this method to be called at the end of a successful sequence of append; all appends are processed before this method is called.

  Specified by:

  commitWritersInternal in class StripeMultiFileWriter

  Throws:

  IOException

• prepareWriterFor

  private void prepareWriterFor(Cell cell)
                         throws IOException

  Throws:

  IOException

• createEmptyWriter

  private void createEmptyWriter()
                          throws IOException

  Called if there are no cells for some stripe. We need to have something in the writer list for this stripe, so that writer-boundary list indices correspond to each other. We can insert null in the writer list for that purpose, except in the following cases where we actually need a file: 1) If we are in range for which we are compacting all the files, we need to create an empty file to preserve stripe metadata. 2) If we have not produced any file at all for this compactions, and this is the last chance (the last stripe), we need to preserve last seqNum (see also HBASE-6059).

  Throws:

  IOException

• checkCanCreateWriter

  private void checkCanCreateWriter()
                             throws IOException

  Throws:

  IOException

• stopUsingCurrentWriter

  private void stopUsingCurrentWriter()
