Description

Failed tests: testWithDirStringAndConf(org.apache.hadoop.fs.shell.TestPathData): checking exist
testToFile(org.apache.hadoop.fs.shell.TestPathData): expected:<file:/tmp> but was:</data/md0/hadoop-common/hadoop-common-project/hadoop-common/target/test/data/testPD/d1>

testWithStringAndConfForBuggyPath (which is declared last and therefore runs last with JDK6) overwrites the static variable testDir with file:///tmp. With JDK7, test methods run in an undefined order, and the other tests will fail if run after this one.
