Subject Re: [JENKINS] Solr-trunk - Build # 1865 - Failure
Date Fri, 25 May 2012 12:11:33 GMT
Just thinking out loud... shouldn't solr(cloud) manage such situation
gracefully? I mean in real life solr instances can be killed or even
whole servers can go away. Would it be ok to ignore that exception
instead?

the webapp, and while we are waiting for merges to finish on IW#close, an interrupt is thrown
and we stop waiting. So the directory is then closed out from under the merge thread. So really,
mostly a test issue it seems?

from 6 minutes for me, to 33 minutes. I won't make this fix for now :) One idea is to perhaps
do it just for this test - but even then it makes the test *much* longer, and there is no
reason it can't happen on other tests that use jetty instances. It just happens to only show
up in the test currently AFAICT.
