Subject [jira] [Created] (HADOOP-14479) Erasurecode testcase failures with ISA-L
Date Fri, 02 Jun 2017 14:28:04 GMT
Ayappan created HADOOP-14479:
--------------------------------

             Summary: Erasurecode testcase failures with ISA-L 
                 Key: HADOOP-14479
                 URL: https://issues.apache.org/jira/browse/HADOOP-14479
             Project: Hadoop Common
          Issue Type: Bug
          Components: common
    Affects Versions: 3.0.0-alpha3
         Environment: x86_64 Ubuntu 16.04.02 LTS
            Reporter: Ayappan


I built hadoop with ISA-L support. I took the ISA-L code from https://github.com/01org/isa-l
 (tag v2.18.0) and built it. While running the UTs , following three testcases are failing

1)TestHHXORErasureCoder
