-----------------------------------------
Summary: Check for Process#waitFor() usage and fix it in order to
avoid indefinite waiting
Key: OOZIE-3359
URL: https://issues.apache.org/jira/browse/OOZIE-3359
Project: Oozie
Issue Type: Improvement
Affects Versions: trunk
Reporter: Julia Kinga Marton
Assignee: Julia Kinga Marton
Fix For: 5.2.0
{{Process#waitFor()}} will block until the process finishes. There are
situations where this will wait indefinitely. A similar case was in
SshActionExecutor, fixed in OOZIE-3354.
Let's check the code for other usages, and fix it.
Maybe we should check if we can use somehow the Process#waitFor(long timeout,
TimeUnit timeUnit) instead of it. The tricky part is that this method is
available only in Java 8.
