Josh Elser updated ACCUMULO-3596: --------------------------------- Description: calls to importDirectory were hanging. After some debugging, it was determined that the imports were stuck waiting on DNS lookups. {{InetAddress#getByName}} calls {{gethostbyname_r}} Further, it was determined that the call only hangs if /etc/host.conf contains "reorder on". A bug was found in this section of the glibc resolver, and a bug report will be made to them. Workaround: turn off address reordering. Many thanks to [~bfloss] for finding this bug. was: calls to importDirectory were hanging.
