John Gordon commented on MAPREDUCE-4377:
----------------------------------------
Thanks Robert! I agree it won't be an easy fix and may need some
rearchitecture and significant test additions.
> 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.
