func (r *Runner) Close() { ...
r.hmapInputProvider.Close()
hmap.go func (i *Input) Close() { i.hostMap.Close() if i.hostMapStream != nil { i.hostMapStream.Close() } }
There seems to be no problem, I wonder if you can help me out? @ehsandeep @Ice3man543
@XTeam-Wing I submitted a PR a long time ago and never waited for the merge
