-----------------------------------------
Summary: Fork-join Error To Transition Can't Reuse Error-To Email
Actions
Key: OOZIE-1142
URL: https://issues.apache.org/jira/browse/OOZIE-1142
Project: Oozie
Issue Type: Bug
Components: workflow
Affects Versions: 3.2.0
Environment: Hadoop 2.0.0-cdh4.1.2
Oozie client build version: 3.2.0-cdh4.1.2
Reporter: Nathaniel Troutman
Workflows that fork and inside the forked paths use the same error-to
transition now fail with the following error:
{noformat}
Error: E0735 : E0735: There was an invalid "error to" transition to node
[send-error-email] while using fork/join
{noformat}
This prevents the workflow from having a single node, used by multiple nodes
within a fork as the error-to transition target, that is responsible for
sending an email before exiting.
The following is a example workflow illustrating this issue:
{code:xml}
<workflow-app xmlns="uri:oozie:workflow:0.2" name="simple">
<start to="prep"/>
<action name="prep">
<fs><delete path='${rootOutpath}'/></fs>
<ok to="fork-it"/>
<error to="send-error-email"/>
</action>
<!-- create two directories -->
<fork name="fork-it">
<path start="path1"/>
<path start="path2"/>
</fork>
<action name="path1">
<fs><mkdir path='${rootOutpath}/path1'/></fs>
<ok to="join-it"/>
<error to="send-error-email"/>
</action>
<action name="path2">
<fs><mkdir path='${rootOutpath}/path2'/></fs>
<ok to="join-it"/>
<error to="send-error-email"/>
</action>
<join name="join-it" to="send-done-email"/>
<action name="send-done-email">
<email xmlns="uri:oozie:email-action:0.1">
<to>${wf:user()}@mail.com</to>
<subject>Oozie Workflow Complete ${wf:name()} on
${clusterName}</subject>
<body>Done</body>
</email>
<ok to="done"/>
<error to="kill"/>
</action>
<action name="send-error-email">
<email xmlns="uri:oozie:email-action:0.1">
<to>${wf:user()}@mail.com</to>
<subject>Oozie Workflow Failure ${wf:name()} action
${wf:lastErrorNode()} on ${clusterName}</subject>
<body>Error Message:
${wf:errorMessage(wf:lastErrorNode())}</body>
</email>
<ok to="done"/>
<error to="kill"/>
</action>
<kill name="kill">
<message>FATAL: unable to send email on action
failure.</message>
</kill>
<end name="done"/>
</workflow-app>
