Virag Kothari commented on OOZIE-1398:
--------------------------------------

Good point. But shouldn't be a problem for now as this column will be reverted 
back from varchar to clob due to a recent issue we faced (OOZIE-1436) 
As <capture-output> should only be used for control data,  one thing that can 
be done is to make the code override the settings of the data length property 
defined in oozie-site if greater than some reasonable value, lets say 4k. In 
that case when converting to varchar(4000) shoudn't be an issue. But probably 
if we are compressing this columns, then we dont even need to do this.
