ketan created HAWQ-1391:
---------------------------

             Summary: s390x support for HWCRC32c
                 Key: HAWQ-1391
                 URL: https://issues.apache.org/jira/browse/HAWQ-1391
             Project: Apache HAWQ
          Issue Type: Bug
          Components: libhdfs
            Reporter: ketan
            Assignee: Ed Espino


Hi ,

I am in progress building Apache - HAWQ on s390x
following instruction on
https://cwiki.apache.org/confluence/display/HAWQ/Build+and+Install

I am in the build stage i notice that during the build i encounter
undefined reference to vtable for Hdfs::Internal::HWCrc32c

On further debugging i observed that  libhdfs3/src/common/HWCRC32c.cpp has not support for s390x.

My questions are as follows.

1) I want to confirm whether does this check happens as part of unit testing of libhdfs3?

2) if yes to 1 whether this test is specific to SSE based platforms ?

3) can we exactly get some information on what this check does>?

Help would be appreciated.

Regards
Ketan
