Wei Zheng created HIVE-16743:
--------------------------------
Summary: 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
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).
