Method Details

setUp

public static void setUp()
                  throws Exception

Throws:

Exception

tearDown

public static void tearDown()
                     throws Exception

Throws:

Exception

testRejectRequestsOnAbort

public void testRejectRequestsOnAbort()
                               throws Exception

Tests that the logic in ServerRpcConnection works such that if the server is aborted, it short circuits any other logic. This means we no longer even attempt to enqueue the request onto the call queue. We verify this by using a special call queue which we can trigger to always return CallQueueTooBigException. If the logic works, despite forcing those exceptions, we should not see them.

Throws:

Exception

getWriterThreadRunnable

private Runnable getWriterThreadRunnable(org.apache.hadoop.hbase.ServerName loadServer)

submitRequestsToRegion

private void submitRequestsToRegion(org.apache.hadoop.hbase.client.Table table,
 org.apache.hadoop.hbase.client.RegionInfo regionInfo)
                             throws IOException

Throws:

IOException

getRowKeyWithin

private byte[] getRowKeyWithin(org.apache.hadoop.hbase.client.RegionInfo regionInfo)
