> TxnIdUtils's [compare|https://github.com/apache/hive/blob/master/storage-api/src/java/org/apache/hive/common/util/TxnIdUtils.java#L38] method returns incorrect result for the following validWriteIdLists
> ValidWriteIdList a = new ValidReaderWriteIdList("default.test:1:1:1:");
>  ValidWriteIdList b = new ValidReaderWriteIdList("default.test:1:9223372036854775807::");
> TxnIdUtils.compare(a, b) returns +1 whereas the expected response is -1 since b is more recent.
