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.
