Change subject: IMPALA-12426: Switches the duration fields to be stored in decimal seconds. ...................................................................... IMPALA-12426: Switches the duration fields to be stored in decimal seconds. The original implementation of the completed queries table stored durations in integer nanoseconds and provided the prettyprint_duration SQL function to format the values into human readable form. This change modifies the duration fields to be stored as seconds with up to three digits of millisecond precision. The prettyprint_duration function would have required a large investment of time to make it work with decimal values, and since the new format is more human readable anyways, this function has been removed. Testing was accomplished by modifying the python custom cluster tests.
