Suresh Srinivas commented on HDFS-1688:
---------------------------------------
Changes to fix the test failures:
# Fault injection test failures:
#* Fixed a bug - In MiniDFSCluster constructor numDatanodes was not initialized
correctly in a previous patch. Instead of depending on startDataNodes method to
increment it to the configured number of datanodes. This initialization
resulted in more number of datanodes than configured. Cluster waits for ever
till the number of datanodes started is equal numDatanodes,
resulting in test failures.
#* Changed fault injection tests to use MiniDFSCluster#Builder instead of
deprecated constructors.
# TestDiskError - change equivalent HADOOP-4679
# TestDatanodeRestart - waiting for datanode to startup is different in
federation with separate threads for block pools. Changed the test for datanode
to fully start.
# TestDFSStartupVersions:
#* In UpgradeUtilities, separated namenode and datanode version creation to
separate methods. When creating datanode version file, blockpool version file
is also created (for federation or releases after that).
#* Added tests that ensures datanode does not come up when the clusterID and
blockPoolID mismatch is found between the datanode and the namenode.
> Federation: Fix failures in fault injection tests, TestDiskError,
