LinuxTaskController doesn't properly escape environment variables
-----------------------------------------------------------------
Key: MAPREDUCE-2242
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2242
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: task-controller
Affects Versions: 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Blocker
LinuxTaskController currently just writes "export FOO=bar" pairs into
taskjvm.sh, which fails if the value has multiple words or contains a space.
This is causing TestDebugScriptWithLinuxTaskController among others to fail on
trunk with the following message:
{code}
export: 1: -Dhadoop.tasklog.iscleanup: bad variable name
{code}
since it generated a taskjvm.sh including the following:
{code}
export
HADOOP_CLIENT_OPTS=-Dhadoop.tasklog.taskid=attempt_20110104180935141_0001_m_000001_0
-Dhadoop.tasklog.iscleanup=false -Dhadoop.tasklog.totalLogFileSize=0
{code}
