Method Details

updateNumTablesInSpaceQuotaViolation

void updateNumTablesInSpaceQuotaViolation(long tablesInViolation)

Updates the metric tracking how many tables this RegionServer has marked as in violation of their space quota.

updateNumTableSpaceQuotaSnapshots

void updateNumTableSpaceQuotaSnapshots(long numSnapshots)

Updates the metric tracking how many tables this RegionServer has received SpaceQuotaSnapshots for.

Parameters:

numSnapshots - The number of SpaceQuotaSnapshots received from the Master.

incrementSpaceQuotaFileSystemScannerChoreTime

void incrementSpaceQuotaFileSystemScannerChoreTime(long time)

Updates the metric tracking how much time was spent scanning the filesystem to compute the size of each region hosted by this RegionServer.

Parameters:

time - The execution time of the chore in milliseconds.

incrementSpaceQuotaRefresherChoreTime

void incrementSpaceQuotaRefresherChoreTime(long time)

Updates the metric tracking how much time was spent updating the RegionServer with the latest information on space quotas from the hbase:quota table.

Parameters:

time - The execution time of the chore in milliseconds.

incrementNumRegionSizeReportsSent

void incrementNumRegionSizeReportsSent(long numReportsSent)

Updates the metric tracking how many region size reports were sent from this RegionServer to the Master. These reports contain information on the size of each Region hosted locally.

Parameters:

numReportsSent - The number of region size reports sent

incrementRegionSizeReportingChoreTime

void incrementRegionSizeReportingChoreTime(long time)

Updates the metric tracking how much time was spent sending region size reports to the Master by the RegionSizeReportingChore.

Parameters:

time - The execution time in milliseconds.
