Method Detail

getMaxSequenceId

public long getMaxSequenceId()

Overrides:

getMaxSequenceId in class StoreFile

Returns:

This files maximum edit sequence id.

isMajorCompaction

public boolean isMajorCompaction()

Overrides:

isMajorCompaction in class StoreFile

Returns:

True if this file was made by a major compaction.

setIsMajor

public void setIsMajor(boolean isMajor)

isReference

public boolean isReference()

Overrides:

isReference in class StoreFile

Returns:

True if this is a StoreFile Reference; call after StoreFile.open() else may get wrong answer.

isBulkLoadResult

public boolean isBulkLoadResult()

Description copied from class: StoreFile

Check if this storefile was created by bulk load. When a hfile is bulk loaded into HBase, we append '_SeqId_' to the hfile name, unless "hbase.mapreduce.bulkload.assign.sequenceNumbers" is explicitly turned off. If "hbase.mapreduce.bulkload.assign.sequenceNumbers" is turned off, fall back to BULKLOAD_TIME_KEY.

Overrides:

isBulkLoadResult in class StoreFile

Returns:

true if this storefile was created by bulk load.

getMetadataValue

public byte[] getMetadataValue(byte[] key)

Description copied from class: StoreFile

Only used by the Striped Compaction Policy

Overrides:

getMetadataValue in class StoreFile

Returns:

value associated with the metadata key

setMetadataValue

public void setMetadataValue(byte[] key,
                             byte[] value)

getMinimumTimestamp

public Long getMinimumTimestamp()

Overrides:

getMinimumTimestamp in class StoreFile

getMaximumTimestamp

public Long getMaximumTimestamp()

Overrides:

getMaximumTimestamp in class StoreFile

getModificationTimeStamp

public long getModificationTimeStamp()

Overrides:

getModificationTimeStamp in class StoreFile

getHDFSBlockDistribution

public HDFSBlocksDistribution getHDFSBlockDistribution()

Overrides:

getHDFSBlockDistribution in class StoreFile

Returns:

the cached value of HDFS blocks distribution. The cached value is calculated when store file is opened.

getReader

public StoreFile.Reader getReader()

Overrides:

getReader in class StoreFile

Returns:

Current reader. Must call createReader first else returns null.
