Sangjin Lee updated YARN-4178:
------------------------------
    Description: 
Currently the app id is used in various places as part of row keys. However, 
currently they are treated as strings. This will cause a problem with ordering 
when the id portion of the app id rolls over to the next digit.

For example, "app_1234567890_10000" will be considered *earlier* than 
"app_1234567890_9999". We should correct this.

Currently the app id is used in various places as part of row keys and in 
column names. However, they are treated as strings for the most part. This will 
cause a problem with ordering when the id portion of the app id rolls over to 
the next digit.

For example, "app_1234567890_100" will be considered *earlier* than 
"app_1234567890_99". We should correct this.
