Method Detail

setRIT

void setRIT(int ritCount)

Set the number of regions in transition.

Parameters:

ritCount - count of the regions in transition.

setRITCountOverThreshold

void setRITCountOverThreshold(int ritCountOverThreshold)

Set the count of the number of regions that have been in transition over the threshold time.

Parameters:

ritCountOverThreshold - number of regions in transition for longer than threshold.

setRITOldestAge

void setRITOldestAge(long age)

Set the oldest region in transition.

Parameters:

age - age of the oldest RIT.

updateRitDuration

void updateRitDuration(long duration)

incrementOperationCounter

void incrementOperationCounter()

TODO: Remove. This may not be needed now as assign and unassign counts are tracked separately Increment the count of operations (assign/unassign).

getAssignMetrics

getUnassignMetrics

org.apache.hadoop.hbase.metrics.OperationMetrics getUnassignMetrics()

Returns:

OperationMetrics containing common metrics for unassign operation

getSplitMetrics

org.apache.hadoop.hbase.metrics.OperationMetrics getSplitMetrics()

Returns:

OperationMetrics containing common metrics for split operation

getMergeMetrics

org.apache.hadoop.hbase.metrics.OperationMetrics getMergeMetrics()

Returns:

OperationMetrics containing common metrics for merge operation
