recovering from el expression failure
Hi,
In my workflow I have a switch that looks like this
<switch>
<case to="Foo">${fs:exists('hdfs://host/path')}</case>
<default to="Bar"/>
</switch>
However the exists el expression can throw an exception when the namenode
is not whiteliisted in oozie.
Unfortunately the whitelist is not under my control and when this exception
is raised I would like it to use the default transition.
Is it possible to do this ?

Unfortunately I don't think so. It's not possible to define an <error>
transition inside the decision or the switch node.
It would be a nice feature though.
