Method Detail

getTableInfo

public HBaseFsck.TableInfo getTableInfo()

Specified by:

getTableInfo in interface TableIntegrityErrorHandler

setTableInfo

public void setTableInfo(HBaseFsck.TableInfo ti2)

Set the TableInfo used by all HRegionInfos fabricated by other callbacks

Specified by:

setTableInfo in interface TableIntegrityErrorHandler

handleRegionStartKeyNotEmpty

public void handleRegionStartKeyNotEmpty(HBaseFsck.HbckInfo hi)
                                  throws IOException

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

Parameters:

hi - An HbckInfo 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

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

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(HBaseFsck.HbckInfo hi)
                            throws IOException

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

Specified by:

handleDegenerateRegion in interface TableIntegrityErrorHandler

Parameters:

hi - An HbckInfo for a degenerate key.

Throws:

IOException

handleDuplicateStartKeys

public void handleDuplicateStartKeys(HBaseFsck.HbckInfo hi1,
                            HBaseFsck.HbckInfo hi2)
                              throws IOException

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

Parameters:

hi1 - one of the overlapping HbckInfo

hi2 - the other overlapping HbckInfo

Throws:

IOException

handleOverlapInRegionChain

public void handleOverlapInRegionChain(HBaseFsck.HbckInfo hi1,
                              HBaseFsck.HbckInfo hi2)
                                throws IOException

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

Parameters:

hi1 - one of the overlapping HbckInfo

hi2 - the other overlapping HbckInfo

Throws:

IOException

handleHoleInRegionChain

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

Callback for handling a region hole between two keys.

Specified by:

handleHoleInRegionChain in interface TableIntegrityErrorHandler

Parameters:

holeStart - key at the beginning of the region hole

holeEnd - key at the end of the region hole

Throws:

IOException

handleOverlapGroup

public void handleOverlapGroup(Collection<HBaseFsck.HbckInfo> overlap)
                        throws IOException

Callback for handling an group of regions that overlap.

Specified by:

handleOverlapGroup in interface TableIntegrityErrorHandler

Parameters:

overlap - Collection of overlapping regions.

Throws:

IOException
