GitHub user nabhanelrahman opened a pull request:
https://github.com/apache/storm/pull/1487
off-by-one error for UNCOMMITTED_LATEST and UNCOMMITTED_EARLIEST
In the source code documentation, it says for both UNCOMMITTED_LATEST
and UNCOMMITTED_EARLIEST it will fetch the last committed offset ( if it
exists ). But the code fetches last committed + 1;
If a topology is killed/crashes and then is redeployed, this off-by-one
error causes one message per partition to be dropped.
