CDH does have that property. In both CDH and Apache distributions, that property (and some others) is specified in oozie-default.xml. There should be a copy of its somewhere. Oozie has its own internal copy of oozie-default.xml, so don't bother editing the one you find; Oozie loads its oozie-default.xml first and then loads oozie-site.xml with any properties you set (Hadoop works the same way with core-default.xml and core-site.xml).
The NPE is because you only have the two services, PurgeService and SchedulerService, loaded because you overrode the oozie.services property. The NPE occurs because Oozie does need the ConfigurationService for sure to work properly; and without many of the other services, it will likely have other issues. You should remove your override of oozie.services from oozie-site.xml. Check oozie-default.xml and see if it lists PurgeService under oozie.services. If it does not, then you can add it in your oozie-site.xml in the oozie.services.ext property; if it does, then the PurgeService is enabled. - Robert On Wed, Oct 2, 2013 at 10:49 AM, Serega Sheypak <[email protected]>wrote: > Hi Robert, thanks for reply. > > Cloudera distirbution doesn't have property oozie.services > 1.
