----------------------------
Resolution: Fixed
> fix DirectoryIterator of libhdfs
> --------------------------------
>
> Key: HAWQ-1769
> URL: https://issues.apache.org/jira/browse/HAWQ-1769
> Project: Apache HAWQ
> Issue Type: Bug
> Components: libhdfs
> Affects Versions: 2.4.0.0
> Reporter: Zuoyan Qin
> Assignee: Ruilong Huo
> Priority: Major
> Fix For: 2.5.0.0
>
>
> The DirectoryIterator of libhdfs has some problems now:
> * even if the `getListing` RPC returns "remainingentries = 0", the following
> invoking of DirectoryIterator::hasNext() may still trigger an *unnecessary*
> `getListing` RPC to the server.
> * moreover, in the above case, if the server returns a non-empty list (so it
> is a server bug because the server should return an empty list) when the
> client send an unnecessary `getListing` RPC, then
> DirectoryIterator::hasNext() will return true, and we will enter endless loop.
