List of std() Examples

Examples of std()

org.apache.hadoop.hbase.client.coprocessor.AggregationClient.std()
This is the client side interface/handle for calling the std method for a given cf-cq combination. It was necessary to add one more call stack as its return type should be a decimal value, irrespective of what columninterpreter says. So, this methods collects the necessary parameters to compute the std and returns the double value. @param tableName @param ci @param scan @return @throws Throwable
org.apache.hadoop.mapred.JobInProgress.DataStatistics.std()
