Method Details

setUpBeforeClass

public static void setUpBeforeClass()
                             throws Exception

Throws:

Exception

createTestTable

private static org.apache.hadoop.hbase.client.Table createTestTable(org.apache.hadoop.hbase.TableName name,
 byte[][] rows,
 byte[][] families,
 byte[][] qualifiers,
 byte[] cellValue)
                                                             throws IOException

Throws:

tearDownAfterClass

public static void tearDownAfterClass()
                               throws Exception

Throws:

Exception

createPuts

private static ArrayList<org.apache.hadoop.hbase.client.Put> createPuts(byte[][] rows,
 byte[][] families,
 byte[][] qualifiers,
 byte[] value)
                                                                 throws IOException

Make puts to put the input value into each combination of row, family, and qualifier

Parameters:

rows - the rows to use

families - the column families to use

qualifiers - the column qualifiers to use

value - the value to put

Returns:

the putted input values added in puts

Throws:

IOException - If an IO problem is encountered

getCellHeapSize

private long getCellHeapSize()
                      throws Exception

Returns:

The approximate heap size of a cell in the test table. All cells should have approximately the same heap size, so the value is cached to avoid repeating the calculation

Throws:

Exception - on unexpected failure

testRowsSeenMetric

public void testRowsSeenMetric()
                        throws Exception

Throws:

Exception

Throws:

Exception

testRowsSeenMetric

private void testRowsSeenMetric(org.apache.hadoop.hbase.client.Scan baseScan)
                         throws Exception

Throws:

Exception

Throws:

Exception

testRowsFilteredMetric

private void testRowsFilteredMetric(org.apache.hadoop.hbase.client.Scan baseScan)
                             throws Exception

Throws:

Exception

Throws:

Exception

testMetric

private void testMetric(org.apache.hadoop.hbase.client.Scan scan,
 String metricKey,
 long expectedValue)
                 throws Exception

Run the scan to completetion and check the metric against the specified value

Parameters:

scan - The scan instance to use to record metrics

metricKey - The metric key name

expectedValue - The expected value of metric

Throws:
