Constructor Detail

RestoreMetaChanges

public RestoreMetaChanges(org.apache.hadoop.hbase.client.TableDescriptor htd,
                          Map<String,org.apache.hadoop.hbase.util.Pair<String,String>> parentsMap)

Method Detail

getTableDescriptor

public org.apache.hadoop.hbase.client.TableDescriptor getTableDescriptor()

getParentToChildrenPairMap

public Map<String,org.apache.hadoop.hbase.util.Pair<String,String>> getParentToChildrenPairMap()

Returns the map of parent-children_pair.

Returns:

the map

hasRegionsToAdd

public boolean hasRegionsToAdd()

Returns:

true if there're new regions

getRegionsToAdd

public List<org.apache.hadoop.hbase.client.RegionInfo> getRegionsToAdd()

Returns the list of new regions added during the on-disk restore. The caller is responsible to add the regions to META. e.g MetaTableAccessor.addRegionsToMeta(...)

Returns:

the list of regions to add to META

hasRegionsToRestore

public boolean hasRegionsToRestore()

Returns:

true if there're regions to restore

getRegionsToRestore

public List<org.apache.hadoop.hbase.client.RegionInfo> getRegionsToRestore()

Returns the list of 'restored regions' during the on-disk restore. The caller is responsible to add the regions to hbase:meta if not present.

Returns:

the list of regions restored

hasRegionsToRemove

public boolean hasRegionsToRemove()

Returns:

true if there're regions to remove

getRegionsToRemove

public List<org.apache.hadoop.hbase.client.RegionInfo> getRegionsToRemove()

Returns the list of regions removed during the on-disk restore. The caller is responsible to remove the regions from META. e.g. MetaTableAccessor.deleteRegions(...)

Returns:

the list of regions to remove from META

updateMetaParentRegions

public void updateMetaParentRegions(org.apache.hadoop.hbase.client.Connection connection,
                                    List<org.apache.hadoop.hbase.client.RegionInfo> regionInfos)
                             throws IOException

Throws:

IOException
