Questions about unit tests: 1) I ran this to execute all tests in the filter package - mvn test -Dtest=org.apache.hadoop.hbase.filter.* The ColumnRangeFilter test fails with this error
------------------------------------------------------------------------------- Test set: org.apache.hadoop.hbase.filter.TestColumnRangeFilter ------------------------------------------------------------------------------- Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 3.136 sec <<< FAILURE! org.apache.hadoop.hbase.filter.TestColumnRangeFilter Time elapsed: 0 sec <<< ERROR! java.lang.NullPointerException at org.apache.hadoop.hdfs.MiniDFSCluster.startDataNodes(MiniDFSCluster.java:422) at org.apache.hadoop.hdfs.MiniDFSCluster.<init>(MiniDFSCluster.java:280) at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniDFSCluster(HBaseTestingUtility.java:449) at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:617) at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:573) at org.apache.hadoop.hbase.HBaseTestingUtility.startMiniCluster(HBaseTestingUtility.java:542) at org.apache.hadoop.hbase.filter.TestColumnRangeFilter.setUpBeforeClass(TestColumnRangeFilter.java:135) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:45) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:42) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:27) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:30) at org.junit.runners.ParentRunner.run(ParentRunner.java:300) at org.junit.runners.Suite.runChild(Suite.java:128) at org.junit.runners.Suite.runChild(Suite.java:24) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:231) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:439) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) at java.util.concurrent.FutureTask.run(FutureTask.java:138) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Is this a permissions issue? 2) I tried to run a single test like this *mvn test -Dtest=org.apache.hadoop.hbase.filter.TestPrefixFilter* and this *mvn test -Dtest=TestPrefixFilter* But that fails with this error Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.12-TRUNK-HBASE-2:test (secondPartTestsExecution) on project hbase: No tests were executed! (Set -DfailIfNoTests=false to ignore this error.) -> [Help 1] What am I doing wrong here?
