    https://issues.apache.org/jira/browse/OOZIE-1737


Repository: oozie-git


Description
-------

User can provide multiple option as -param <>;<>;<> to make streaming faster 
and precise.
Option can be.
   * Recent: Define offset of recent hours/Min of log to stream. Server will 
search user query only in recent log duration.
   * Start: Start time of log parsing. Oozie server will start parsing logs 
from start date. User can provide a valid date or
     offset.
   * End: Server will streaming logs till specified end date. User can provide 
a valid date or offset.
   * Loglevel : Multiple log levels separated by "|" can be specified.
   * Text: String to search in logs.
   * Limit : Limit number of line to be searched. Log search will end when when 
n lines(excluding exception) of patten has 
     matched.
   * Debug : Will print log start and end time. This will be useful, if user 
are not sure what his/her offset will be
     calculated to.


In addition to this 
1. System setting to control log streaming duration.
2. Added a option to show log streaming status.
   A label on UI will show if log streaming is in progress, completed or erred.
3. Many user has complied that get button doesn't look like button. Changes the 
look of "get log" button.
4. End the execution when data is date is reached.
   earlier started date and end date is only used to load logs files.
