Method Detail

isHealthy

public boolean isHealthy()

DFS is considered healthy if there are no missing blocks.

addMissing

public void addMissing(String id,
                       long size)

Add a missing block name, plus its size.

public ArrayList<String> getMissingIds()

Return a list of missing block names (as list of Strings).

getMissingSize

public long getMissingSize()

Return total size of missing data, in bytes.

setMissingSize

public void setMissingSize(long missingSize)

getOverReplicatedBlocks

public long getOverReplicatedBlocks()

Return the number of over-replicated blocks.

setOverReplicatedBlocks

public void setOverReplicatedBlocks(long overReplicatedBlocks)

getReplicationFactor

public float getReplicationFactor()

Return the actual replication factor.

getUnderReplicatedBlocks

public long getUnderReplicatedBlocks()

Return the number of under-replicated blocks. Note: missing blocks are not counted here.
