             Summary: TxnIdUtils.checkEquivalentWriteIds may return false negatives
                 Key: HIVE-19893
                 URL: https://issues.apache.org/jira/browse/HIVE-19893
             Project: Hive
          Issue Type: Bug
          Components: Transactions
            Reporter: Jesus Camacho Rodriguez


Observed while working on HIVE-19876.

Following two lists are equivalent:
{noformat}
2:2:2: (hwm:2, minOpenId:2, openTxns:2)
2:9223372036854775807:: (hwm:2, minOpenId:none)
{noformat}

However, {{checkEquivalentWriteIds}} will return false, i.e., not equivalent.
