--------------------------------------
Summary: TaskRunner javaopts parsing doesn't handle embedded spaces
Key: MAPREDUCE-4377
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4377
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: task-controller
Affects Versions: trunk
Environment: java options containing escaped or non-escaped embedded
spaces.
Reporter: John Gordon
TaskRunner::GetVMArgs reads getChildJavaOpts as one space-delimited string,
then split is on ' ' and tries to reason on individual options from there. The
problem with this approach is that java options may contain embedded spaces in
many legitimate cases -- this means it is reasoning on incomplete option
strings and cannot do appropriate preprocessing to do things like handle escape
characters or matched quotation marks.
