long getPersistJobId()

Returns:

the job id of the job persisting this file

getShouldPersistTime

long getShouldPersistTime()

Returns:

the time that this file should start persisting

getReplicationDurable

int getReplicationDurable()

Returns:

the durable number of block replication

getReplicationMax

int getReplicationMax()

Returns:

the maximum number of block replication

getReplicationMin

int getReplicationMin()

Returns:

the minimum number of block replication

getTempUfsPath

String getTempUfsPath()

the temporary UFS path this file is persisted to

getBlockIds

List<Long> getBlockIds()

Returns:

a duplication of all the block ids of the file

getBlockSizeBytes

long getBlockSizeBytes()

Returns:

the block size in bytes

getLength

long getLength()

Returns:

the length of the file in bytes. This is not accurate before the file is closed

getBlockContainerId

long getBlockContainerId()

Returns:

the block container ID for this inode file

getBlockIdByIndex

long getBlockIdByIndex(int blockIndex)
                throws BlockInfoException

Gets the block id for a given index.

Parameters:

blockIndex - the index to get the block id for

Returns:

the block id for the index

Throws:

BlockInfoException - if the index of the block is out of range

isCacheable

boolean isCacheable()

Returns:

true if the file is cacheable, false otherwise

isCompleted

boolean isCompleted()
