• archiveRegion

  public static boolean archiveRegion(org.apache.hadoop.fs.FileSystem fs,
                      org.apache.hadoop.fs.Path rootdir,
                      org.apache.hadoop.fs.Path tableDir,

                               throws IOException

  Remove an entire region from the table directory via archiving the region's hfiles.

  Parameters:

  fs - FileSystem from which to remove the region

  rootdir - Path to the root directory where hbase files are stored (for building the archive path)

  tableDir - Path to where the table is being stored (for building the archive path)

  regionDir - Path to where a region is being stored (for building the archive path)

  Returns:

  true if the region was sucessfully deleted. false if the filesystem operations could not complete.

  Throws:

  IOException - if the request cannot be completed

• archiveFamily

  public static void archiveFamily(org.apache.hadoop.fs.FileSystem fs,
                   org.apache.hadoop.conf.Configuration conf,

                   byte[] family)
                            throws IOException

  Remove from the specified region the store files of the specified column family, either by archiving them or outright deletion

  Parameters:

  fs - the filesystem where the store files live

  conf - Configuration to examine to determine the archive directory

  parent - Parent region hosting the store files

  tableDir - Path to where the table is being stored (for building the archive path)

  family - the family hosting the store files

  Throws:

  IOException - if the files could not be correctly disposed.

• archiveStoreFiles

  public static void archiveStoreFiles(org.apache.hadoop.conf.Configuration conf,
                       org.apache.hadoop.fs.FileSystem fs,
                       HRegionInfo regionInfo,
                       org.apache.hadoop.fs.Path tableDir,
                       byte[] family,
                       Collection<StoreFile> compactedFiles)
                                throws IOException,
                                       FailedArchiveException

  Remove the store files, either by archiving them or outright deletion

  Parameters:

  conf - Configuration to examine to determine the archive directory

  fs - the filesystem where the store files live

  regionInfo - HRegionInfo of the region hosting the store files

  family - the family hosting the store files

  compactedFiles - files to be disposed of. No further reading of these files should be attempted; otherwise likely to cause an IOException

  Throws:

  IOException - if the files could not be correctly disposed.

  FailedArchiveException
