Subject Re: Yesterday's date value in Falcon
Date Wed, 05 Aug 2015 09:29:03 GMT
Rishav,
Srikanth just pointed out that I was mistaken. Although Falcon doesn't
evaluate the property values, the EL expressions should be resolved by
Oozie itself. For this to happen, the following has to be place:
1. Oozie installation must have falcon-oozie-el-extension-*.jar under its
libext and also the WAR must have it too.
2. Oozie's oozie-site.xml must be updated with appropriate settings for the
EL expression to be resolved.

Both the jar and the sample oozie-site.xml should be available under
$FALCON_INSTALL_DIR/oozie

Can you please check if the above configuration is taken care of. I will
try this out on my dev environment, in the meanwhile.

Apologies for the confusion,
Regards,
Pallavi
