[jira] [Comment Edited] (ASTERIXDB-2196) MultiPartitionLSMIndexTest
sporadically fails
[ https://issues.apache.org/jira/browse/ASTERIXDB-2196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16331250#comment-16331250 ]

--------------------------------------------------------------
Located the problem, which is a test case timing issue related to the insertion and flush thread. However, it also reveals another problem that it's possible (though very rare) that a primary index can be flushed without flushing secondary indexes because of sharing op tracker for multiple partitions.
All these problems would disappear once we separate the op tracker for each partition ([https://asterix-gerrit.ics.uci.edu/#/c/2263/]).
