-------------------------------------------------------------------------
I included the fix in HIVE-19876. Instead of changing comparison method, it
seemed to me more logical to change the method that generates the IDs, it does
not make sense to include the high watermark in the list of open txns.

> Following two lists are equivalent:
> {noformat}
> default.tbl:2:2:2: (hwm:2, minOpenId:2, openTxns:[2])
> default.tbl:2:9223372036854775807:: (hwm:2, minOpenId:none)
> {noformat}
> However, {{checkEquivalentWriteIds}} will return false, i.e., not equivalent.
