RestoreMetaChanges

public RestoreMetaChanges(TableDescriptor htd,
                          Map<String,Pair<String,String>> parentsMap)

方法详细资料

getTableDescriptor

public TableDescriptor getTableDescriptor()

getParentToChildrenPairMap

public Map<String,Pair<String,String>> getParentToChildrenPairMap()

Returns the map of parent-children_pair.

返回:

the map

hasRegionsToAdd

public boolean hasRegionsToAdd()

返回:

true if there're new regions

getRegionsToAdd

public List<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(...)

返回:

the list of regions to add to META

hasRegionsToRestore

public boolean hasRegionsToRestore()

返回:

true if there're regions to restore

getRegionsToRestore

public List<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.

返回:

the list of regions restored

hasRegionsToRemove

public boolean hasRegionsToRemove()

返回:

true if there're regions to remove

getRegionsToRemove

public List<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(...)

返回:

the list of regions to remove from META

updateMetaParentRegions

public void updateMetaParentRegions(Connection connection,
                                    List<RegionInfo> regionInfos)
                             throws IOException

抛出:

IOException
