Robert Kanter updated OOZIE-1227:
---------------------------------
Attachment: OOZIE-1227.patch
The patch simply skips the check if the scheme is null; I also added some unit
tests and manually verified that it works correctly.
> In a coordinator, specifying the <app-path> without a namenode causes it to
> fail
> --------------------------------------------------------------------------------

> Key: OOZIE-1227
> URL: https://issues.apache.org/jira/browse/OOZIE-1227
> Project: Oozie
> Issue Type: Bug
> Affects Versions: 3.3.0
> Reporter: Robert Kanter
> Assignee: Robert Kanter
> Fix For: trunk, 3.3.2
>
> Attachments: OOZIE-1227.patch

> In a coordinator, some users don't specify the name node in the path to the
> workflow application. e.g.
> {code}
> <action>
> <workflow>
>
> <app-path>/user/${coord:user()}/${examplesRoot}/apps/aggregator</app-path>
> ...
> {code}
> This now causes the coordinator to fail. I think this may also affect other
> paths because many of them go through the HadoopAccessorService.
> Ideally, we should fix this behavior to the old way: have it default to HDFS
> and get the namenode automatically if no scheme://host:port is given.
> A workaround is to to add the following property to oozie-site.xml
> {code}
> <property>
> <name>oozie.service.HadoopAccessorService.supported.filesystems</name>
> <value>*</value>
> </property>
> {code}
> This causes Oozie to effectively have the old behavior. The downside of this
> workaround is that administrators cannot restrict the filesystems that Oozie
> will allow ({{*}} means all filesystems, even non-real ones).
> Instead of making users use that workaround, we can simply make Oozie skip
> the check if the scheme is {{null}}. It would allow the old behavior without
> disabling the scheme check.
