Subject [jira] [Commented] (HADOOP-11410) make the rpath of libhadoop.so configurable
Date Tue, 16 Dec 2014 01:11:48 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11410?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14247546#comment-14247546

Colin Patrick McCabe commented on HADOOP-11410:

bq. Patch looks pretty good to me, Colin. Can you perhaps comment on what testing you've done
of this change? It seems quite straightforward to me, but it'd be good if you could let us
know what verification of this you've done.

I built with and without {{\-Dextra.libhadoop.rpath=/tmp/foo}} and verified that the RPATH
was as expected using {{chrpath -l}}

One small suggestion on the actual contents of the patch: given that we're now adding $ORIGIN
into the RPATH before the SET_TARGET_PROPERTIES call, seems like it'd be better to move the
associated comment explaining the purpose of that up as well.

> We should make the rpath of {{libhadoop.so}} configurable, so that we can use a different
rpath if needed.  The {{RPATH}} of {{libhadoop.so}} is primarily used to control where {{dlopen}}
looks for shared libraries by default.
