Todd Lipcon updated HDFS-3985:
------------------------------
Attachment: hdfs-3985-timeouts.txt
Attached patch adds 120sec timeouts to all the test cases in this suite.
The last nightly run took 145 seconds, and a run on my laptop had these timings:
{code}
<testcase time="25.516"
classname="org.apache.hadoop.hdfs.server.datanode.TestMultipleNNDataBlockScanner"
name="testDataBlockScanner"/>
<testcase time="21.932"
classname="org.apache.hadoop.hdfs.server.datanode.TestMultipleNNDataBlockScanner"
name="testBlockScannerAfterRefresh"/>
<testcase time="26.999"
classname="org.apache.hadoop.hdfs.server.datanode.TestMultipleNNDataBlockScanner"
name="testBlockScannerAfterRestart"/>
<testcase time="51.206"
classname="org.apache.hadoop.hdfs.server.datanode.TestMultipleNNDataBlockScanner"
name="test2NNBlockRescanInterval"/>
<testcase time="20.61"
classname="org.apache.hadoop.hdfs.server.datanode.TestMultipleNNDataBlockScanner"
name="testBlockRescanInterval"/>
{code}
So 120sec should be plenty of time to not inflict false errors but hopefully
will catch the next time it gets "stuck"
