Subject [jira] Commented: (LUCENE-2721) Random Failure TestSizeBoundedOptimize#testFirstSegmentTooLarge
Date Sat, 23 Oct 2010 13:21:18 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2721?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12924196#action_12924196
] 

Shai Erera commented on LUCENE-2721:
------------------------------------

What do you mean? If maxBufDocs is set low enough (as in this case), the tests that rely on
the segments size as committed by them would fail. In fact, all tests care - if I rely on
a segment size to be 3, and set maxMergeDocs to 2, but because of randomness there were 2
segments of size 2 + 1, then the test would fail.
