> 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
> {code:java}
> 1) java.lang.NumberFormatException: For input string: ""
> OR
> java.lang.NumberFormatException: For input string: ".821582E.821582E44"
> OR
> 2) Caused by: java.lang.ArrayIndexOutOfBoundsException: -5325980

> sun.util.calendar.BaseCalendar.getCalendarDateFromFixedDate(BaseCalendar.java:453)
> at
> java.util.GregorianCalendar.computeFields(GregorianCalendar.java:2397)
> {code}
> This issue is to address those thread-safety issues/race conditions.
