Subject [jira] [Commented] (SOLR-11426) TestLazyCores fails too often
Date Tue, 10 Oct 2017 15:51:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-11426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16198871#comment-16198871

Erick Erickson commented on SOLR-11426:
---------------------------------------

OK, no failures on master since this latest info-gathering code was committed to master, which
is kind of scary as this isn't a proper fix at all.

All the latest test does is fire a commit whenever a transient core is aged out. I expected
that just the normal core closing would issue a commit, and it seems to, just not all the
time apparently Which means there's some circumstance where a core could lose documents that
haven't been committed when it is closed.

So the underlying issue is (apparently) there is some condition where uncommitted changes
are not committed on a core close. I'll be looking some more, but would certainly welcome
any ideas/help.

Meanwhile I'll leave the code in for a bit just to see if I'm getting (un)lucky with this
test and happening to succeed for a few days. If it continues to succeed through tonight I'll
revert tomorrow and insure it comes back.

> Rather then re-opening SOLR-10101 I thought I'd start a new issue. I may have to put
some code up on Jenkins to test, last time I tried to get this to fail locally I couldn't
