tejaswini-imply 70c40c4281 Fix long overflow in SegmentCostCache.Bucket.toLocalInterval (#12257 ) Problem: When using a `CachingCostBalancerStrategy` with segments of granularity ALL, no segment gets loaded. - With granularity ALL, segments of eternity interval are created which have `start = Long.MIN_VALUE / 2` and `end = Long.MAX_VALUE / 2`. - For cost calculation in the balancer strategy, `toLocalInterval()` method is invoked where `Long.MIN_VALUE / 2` or `Long.MAX_VALUE / 2` cause an overflow thus resulting in no overlap. - The strategy is unable to find any eligible server for loading a given segment. Fix: - Reverse order of operations to divide by `MILLIS_FACTOR` (~10^8) first, then do the subtraction to prevent Long overflow.	2022-02-17 15:13:51 +05:30

Fix long overflow in SegmentCostCache.Bucket.toLocalInterval (#12257 )

Problem:
When using a `CachingCostBalancerStrategy` with segments of granularity ALL,
no segment gets loaded.
- With granularity ALL, segments of eternity interval are created which have 
  `start = Long.MIN_VALUE / 2` and `end = Long.MAX_VALUE / 2`.
- For cost calculation in the balancer strategy, `toLocalInterval()` method is invoked where
  `Long.MIN_VALUE / 2` or `Long.MAX_VALUE / 2` cause an overflow thus resulting in no overlap.
- The strategy is unable to find any eligible server for loading a given segment.

Fix:
- Reverse order of operations to divide by `MILLIS_FACTOR` (~10^8) first,
   then do the subtraction to prevent Long overflow.
