ACCUMULO-4834 exposed a merge bug from ACCUMULO-4777. ACCUMULO-4777 added a parameter to the two Retry constructors, but since all the parameters are longs, this masked what should have been a compile failure by causing calls to the longer constructor to now use the shorter one.
The side effect is that any calls with "unlimited number of retries", would now be interpreted as "unlimited wait time between retries"... causing the first failure to sleep for Long.MAX_LONG millis before retrying.
I propose a refactor with a builder so the parameters cannot be confused for one another, since they all have the same long type. This is internal code, so there is no public API change.
