Method Detail

appendMetadata

public void appendMetadata(long maxSequenceId,
                           boolean majorCompaction)
                    throws java.io.IOException

Writes meta data. Call before close() since its written as meta data to this file.

Parameters:

maxSequenceId - Maximum sequence id.

majorCompaction - True if this file is product of a major compaction

Throws:

java.io.IOException - problem writing to FS

appendMetadata

public void appendMetadata(long maxSequenceId,
                           boolean majorCompaction,
                           long mobCellsCount)
                    throws java.io.IOException

Writes meta data. Call before close() since its written as meta data to this file.

Parameters:

maxSequenceId - Maximum sequence id.

majorCompaction - True if this file is product of a major compaction

mobCellsCount - The number of mob cells.

Throws:

java.io.IOException - problem writing to FS

appendTrackedTimestampsToMetadata

public void appendTrackedTimestampsToMetadata()
                                       throws java.io.IOException

Add TimestampRange and earliest put timestamp to Metadata

Throws:

java.io.IOException
