Class org.apache.hadoop.hive.ql.stats.StatsAggregator

Examples of org.apache.hadoop.hive.ql.stats.StatsAggregator.aggregateStats()

org.apache.hadoop.hive.ql.stats.StatsAggregator.aggregateStats()
This method aggregates a given statistic from all tasks (partial stats). After aggregation, this method also automatically removes all records that have been aggregated. @param keyPrefix a prefix of the keys used in StatsPublisher to publish stats. Any rows that starts with the same prefix will be aggregated. For example, if the StatsPublisher uses the following compound key to publish stats: the output directory name (unique per FileSinkOperator) + the partition specs (only for dynamic partitions) + taskID (last component of task file) The keyPrefix for aggregation could be first 2 components. This will aggregates stats across all tasks for each partition. @param statType a string noting the key to be published. Ex: "numRows". @return a string representation of a long value, null if there are any error/exception.
