Status: Patch Available (was: Open)
> BitSet set() is not incorrectly used in TxnUtils.createValidCompactTxnList()
>
>
> Key: HIVE-16743
> URL: https://issues.apache.org/jira/browse/HIVE-16743
> Project: Hive
> Issue Type: Bug
> Components: Transactions
>Affects Versions: 3.0.0
>Reporter: Wei Zheng
>Assignee: Wei Zheng
> Attachments: HIVE-16743.1.patch
>
>
> The second line is problematic
> {code}
> BitSet bitSet = new BitSet(exceptions.length);
> bitSet.set(0, bitSet.length()); // for ValidCompactorTxnList, everything
> in exceptions are aborted
> {code}
> For example, exceptions' length is 2. We declare a BitSet object with initial
> size of 2 via the first line above. But that's not the actual size of the
> BitSet. So bitSet.length() will still return 0.
> The intention of the second line above is to set all the bits to true. This
> was not achieved because bitSet.set(0, bitSet.length()) is equivalent to
> bitSet.set(0, 0).
