Method Details

testRow

boolean testRow(int i,
 long startTime)
         throws IOException

Description copied from class: PerformanceEvaluation.TestBase

Test for individual row.

Specified by:

testRow in class PerformanceEvaluation.TestBase

Parameters:

i - Row index.

Returns:

true if the row was sent to server and need to record metrics. False if not, multiGet and multiPut e.g., the rows are sent to server only if enough gets/puts are gathered.

Throws:

IOException

getStartAndStopRow

protected abstract org.apache.hadoop.hbase.util.Pair<byte[],byte[]> getStartAndStopRow()

generateStartAndStopRows

protected org.apache.hadoop.hbase.util.Pair<byte[],byte[]> generateStartAndStopRows(int maxRange)

getReportingPeriod

protected int getReportingPeriod()

Overrides:
