Description

HIVE-22405 added support for proleptic calendar. It uses java's SimpleDateFormat/Calendar APIs which are not thread-safe and cause race in some scenarios.

As a result of those race conditions, we see some exceptions like

1) java.lang.NumberFormatException: For input string: "" 
OR 
java.lang.NumberFormatException: For input string: ".821582E.821582E44"

OR

2) Caused by: java.lang.ArrayIndexOutOfBoundsException: -5325980
    	at sun.util.calendar.BaseCalendar.getCalendarDateFromFixedDate(BaseCalendar.java:453)
    	at java.util.GregorianCalendar.computeFields(GregorianCalendar.java:2397)

This issue is to address those thread-safety issues/race conditions.
