I'm trying to export the oozie workflows/coordinators/bundles from HUE3.9 version and import into HUE4.2 version.
I'm using exporting and importing via UI, not command line.
When importing to the most recent version, is complains about Invalid JSON. Looking into the logs i see that it refers to a missing field "parent_directory" that i don't see in 3.9 DB but is now in 4.2.
