Subject [jira] [Commented] (YARN-3422) relatedentities always return empty list when primary filter is set
Date Sat, 02 May 2015 19:05:06 GMT

    [ https://issues.apache.org/jira/browse/YARN-3422?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14525410#comment-14525410

Billie Rinaldi commented on YARN-3422:

Let’s say we post entity A with related entity B and primary filter C.  This implies a directional
relationship B -> A.  The entries stored include the following:
entity entry: A (with hidden B)
related entity entry: B A
primary filter entry: C A (no B)
The patch submitted adds primary filter entry C B A, which is not correct for the existing
design because C was posted as a primary filter for A, not for B.  What we might want (that
the store does not currently do) is for A to be added under primary filter entries for B (i.e.
D B A, where D is a primary filter for B).  One problem with doing this is that we do not
know the primary filters for B when we are posting entity A, and a further problem is that
the primary filters for B could change over time and have to be kept up to date.
