Method Detail

handleRegionStartKeyNotEmpty

public void handleRegionStartKeyNotEmpty(HbckRegionInfo hi)
                                  throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling case where a Table has a first region that does not have an empty start key.

Specified by:

handleRegionStartKeyNotEmpty in interface TableIntegrityErrorHandler

Overrides:

handleRegionStartKeyNotEmpty in class TableIntegrityErrorHandlerImpl

Parameters:

hi - An HbckRegionInfo of the second region in a table. This should have a non-empty startkey, and can be used to fabricate a first region that has an empty start key.

Throws:

IOException

handleRegionEndKeyNotEmpty

public void handleRegionEndKeyNotEmpty(byte[] curEndKey)
                                throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling case where a Table has a last region that does not have an empty end key.

Specified by:

handleRegionEndKeyNotEmpty in interface TableIntegrityErrorHandler

Overrides:

handleRegionEndKeyNotEmpty in class TableIntegrityErrorHandlerImpl

Parameters:

curEndKey - The end key of the current last region. There should be a new region with start key as this and an empty end key.

Throws:

IOException

handleDegenerateRegion

public void handleDegenerateRegion(HbckRegionInfo hi)
                            throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling a region that has the same start and end key.

Specified by:

handleDegenerateRegion in interface TableIntegrityErrorHandler

Overrides:

handleDegenerateRegion in class TableIntegrityErrorHandlerImpl

Parameters:

hi - An HbckRegionInfo for a degenerate key.

Throws:

IOException

handleDuplicateStartKeys

public void handleDuplicateStartKeys(HbckRegionInfo r1,
                                     HbckRegionInfo r2)
                              throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling two regions that have the same start key. This is a specific case of a region overlap.

Specified by:

handleDuplicateStartKeys in interface TableIntegrityErrorHandler

Overrides:

handleDuplicateStartKeys in class TableIntegrityErrorHandlerImpl

Parameters:

r1 - one of the overlapping HbckRegionInfo

r2 - the other overlapping HbckRegionInfo

Throws:

IOException

handleSplit

public void handleSplit(HbckRegionInfo r1,
                        HbckRegionInfo r2)
                 throws IOException

Description copied from interface: TableIntegrityErrorHandler

Callback for handling two regions that have the same regionID a specific case of a split

Parameters:

r1 - one of the overlapping HbckRegionInfo

r2 - the other overlapping HbckRegionInfo

Throws:

IOException

handleOverlapInRegionChain

public void handleOverlapInRegionChain(HbckRegionInfo hi1,
                                       HbckRegionInfo hi2)
                                throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling two reigons that overlap in some arbitrary way. This is a specific case of region overlap, and called for each possible pair. If two regions have the same start key, the handleDuplicateStartKeys method is called.

Specified by:

handleOverlapInRegionChain in interface TableIntegrityErrorHandler

Overrides:

handleOverlapInRegionChain in class TableIntegrityErrorHandlerImpl

Parameters:

hi1 - one of the overlapping HbckRegionInfo

hi2 - the other overlapping HbckRegionInfo

Throws:

IOException

handleHoleInRegionChain

public void handleHoleInRegionChain(byte[] holeStart,
                                    byte[] holeStop)
                             throws IOException

Description copied from class: TableIntegrityErrorHandlerImpl

Callback for handling a region hole between two keys.

Specified by:

handleHoleInRegionChain in interface TableIntegrityErrorHandler

Overrides:

handleHoleInRegionChain in class TableIntegrityErrorHandlerImpl

Parameters:

holeStart - key at the beginning of the region hole

holeStop - key at the end of the region hole

Throws:

IOException
