-------------------------------------
Summary: DefaultTaskController fails to launch tasks on Windows
Key: MAPREDUCE-4321
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4321
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 1.0.0
Reporter: Ivan Mitic
Assignee: Ivan Mitic
DefaultTaskController#launchTask tries to run the child JVM task with the
following command line:
{code}cmd.exe /c /c:/some/path.../taskjvm.cmd{code}
And this fails because the given path is prefixed with a forward slash. This
also causes a number of tests to fail:
org.apache.hadoop.conf.TestNoDefaultsJobConf
org.apache.hadoop.fs.TestCopyFiles
org.apache.hadoop.mapred.TestBadRecords
org.apache.hadoop.mapred.TestClusterMRNotification
org.apache.hadoop.mapred.TestCompressedEmptyMapOutputs
org.apache.hadoop.mapred.TestControlledMapReduceJob
org.apache.hadoop.mapred.TestCustomOutputCommitter
org.apache.hadoop.mapred.TestEmptyJob
org.apache.hadoop.mapred.TestFileOutputFormat
org.apache.hadoop.mapred.TestIsolationRunner
org.apache.hadoop.mapred.TestJavaSerialization
org.apache.hadoop.mapred.TestJobCleanup
org.apache.hadoop.mapred.TestJobCounters
org.apache.hadoop.mapred.TestJobHistoryServer
org.apache.hadoop.mapred.TestJobInProgressListener
org.apache.hadoop.mapred.TestJobKillAndFail
org.apache.hadoop.mapred.TestJobName
