Subject [jira] [Commented] (HADOOP-11887) Introduce Intel ISA-L erasure coding library for the native support
Date Fri, 05 Jun 2015 23:21:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14575391#comment-14575391

Greg Tucker commented on HADOOP-11887:
--------------------------------------

Alan,

Sorry about the confusion. The make test target for ISA-L is just a bit too inclusive now
and tries to build and run all the arch-specific tests on any machine.  This unfortunately
includes tests that explicitly call a version with AVX that will certainly fail on a machine
without AVX support.  This doesn't mean that the multi-binary functions don't to the right
thing and run an appropriate version.  We will be sure in the next release that make test
doesn't try to run all these cross-arch tests.
