Erick Erickson commented on SOLR-8135:
--------------------------------------
This feels a little like a band-aid. If I'm reading this right, the sequence is
this:
1> the test changes the configs, kicking off reloads for the cores
2> the test deletes the collection
<2> happens before <1> is complete, thus the race as the reload doesn't get
around to reloading the core after the delete happens and the core is closed.
Is this about right?
Tim's comment about a delay suggests that if we waited for the config changes
to complete reloading before continuing the test we'd be OK. It seems like a
better option would be to have Solr not start the delete while reloads were
pending. Or more generally not start carrying out one command while another
potentially conflicting operation was being carried.
Not sure how hard having Solr be smart enough to delay "potentially
conflicting" operations would be though.
