Rohini Palaniswamy commented on OOZIE-1073:
-------------------------------------------

Review request in https://reviews.apache.org/r/8283/. Removed the patch with fix for bug in latest and future when the oozie processing timezone was different than UTC. Handling that in a separate jira - OOZIE-1106.

> Assuming all 24 instances are available, Oozie makes 300(1+2+3+..24) calls instead of 24 calls. This leads to some very high CPU usage when number of latest instances is high.
