athanatos opened a new issue #865: LongHierarchicalLedgerManager: fix race with concurrent updates in initialize() URL: https://github.com/apache/bookkeeper/issues/865 LongHierarchicalLedgerRangeIterator.initialize() can erroneously exit with iteratorDone if the lexicographically first path in zk has fewer than 4 levels. This can happen for a few reasons including a case where a client creating a ledger on that path crashed during the zk updates or the iterator.hasNext() call simply raced with an in-progress node creation or removal. ScanAndCompareGarbageCollector is hasNext() returns false will delete all ledgers on the bookie, so this is a fairly serious bug.
