[MAPREDUCE-2242] LinuxTaskController doesn't properly escape environment variables

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 0.22.0
• Component/s: task-controller
• Assignee: Todd Lipcon

Description

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:

export: 1: -Dhadoop.tasklog.iscleanup: bad variable name

since it generated a taskjvm.sh including the following:

export HADOOP_CLIENT_OPTS=-Dhadoop.tasklog.taskid=attempt_20110104180935141_0001_m_000001_0 -Dhadoop.tasklog.iscleanup=false -Dhadoop.tasklog.totalLogFileSize=0
