-------------------------------------

Hi Ted,

Using the tool I was advertising in HADOOP-11045 (and you suggested the location to put the
tool), here is what I got for this job:

{code}
[yzhang@localhost jenkinsftf]$ ./determine-flaky-tests-hadoop.py -j Hadoop-Hdfs-trunk -n 14
****Recently FAILED builds in url: https://builds.apache.org//job/Hadoop-Hdfs-trunk
    THERE ARE 2 builds (out of 5) that have failed tests in the past 14 days, as listed below:

===>https://builds.apache.org/job/Hadoop-Hdfs-trunk/1896/testReport (2014-10-09 04:30:40)
    Failed test: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testDataNodeMetrics
    Failed test: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testRoundTripAckMetric
    Failed test: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testSendDataPacketMetrics
    Failed test: org.apache.hadoop.hdfs.server.namenode.ha.TestDNFencingWithReplication.testFencingStress
    Failed test: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testReceivePacketMetrics
===>https://builds.apache.org/job/Hadoop-Hdfs-trunk/1895/testReport (2014-10-08 04:30:40)
    Failed test: org.apache.hadoop.hdfs.server.namenode.ha.TestDNFencingWithReplication.testFencingStress

Among 5 runs examined, all failed tests <#failedRuns: testName>:
    2: org.apache.hadoop.hdfs.server.namenode.ha.TestDNFencingWithReplication.testFencingStress
    1: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testReceivePacketMetrics
    1: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testSendDataPacketMetrics
    1: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testRoundTripAckMetric
    1: org.apache.hadoop.hdfs.server.datanode.TestDataNodeMetrics.testDataNodeMetrics
[yzhang@localhost jenkinsftf]$ 
{code}

The failure you reported here is likely introduced by the commits happened in between:
===>https://builds.apache.org/job/Hadoop-Hdfs-trunk/1896/testReport (2014-10-09 04:30:40)
===>https://builds.apache.org/job/Hadoop-Hdfs-trunk/1895/testReport (2014-10-08 04:30:40)

Thanks.
