------------------------------------
Summary: Cache the list of available timezones from the admin
servlet
Key: OOZIE-1599
URL: https://issues.apache.org/jira/browse/OOZIE-1599
Project: Oozie
Issue Type: Improvement
Affects Versions: trunk
Reporter: Robert Kanter
Fix For: trunk
The admin servlet has a call that returns a list of available timezones. On
startup, it prepares a list of GMT offsets (e.g. "GMT-12:00", "GMT-11:00",
etc), which is only generated once. But the rest of the timezones (e.g.
"America/Los_Angeles", etc) are processed from {{TimeZone}} every time the
admin servlet is asked for the list.
We should refactor this to generate/process the entire list either the first
time its called or at startup and then simply return the {{JSONArray}} when the
admin servlet is asked for the list.
