Description

While making NameLookupClient injectable in REEF-703, and removing the deprecated Constructor in REEF-1124, replyLookupQueue has become NOT shared between NameClient and NameLookupClient. A question regarding this was actually raised by MariiaMykhailova at REEF-703, but the JIRA was resolved without a clear answer.

This change has not caused any problem in OSX, Windows, and Travis CI's Ubuntu. In other Ubuntu machines, however, reef-io tests fail due to “too many open files” exception. Tests passed on my Ubuntu VM by increasing the maximum number of open files with “ulimit -n 9999” command.

But increasing the maximum number is just a workaround; I think a cleaner solution will be to share replyLookupQueue as we used to. Any thought?
