Subject 2.7.3 shipped without Snappy support
Date Sat, 01 Oct 2016 02:46:38 GMT
Hi there,
Why are releases up to 2.7.2 shipped with a libhadoop.so built with Snappy
support but 2.7.3 not?  I couldn’t find anything in the release notes or ML
archives that would indicate that this was an intentional change.

hadoop-2.7.2/lib/native/libhadoop.so.1.0.0:
0000000000014fb0 <Java_org_apache_hadoop_util_NativeCodeLoader_
buildSupportsSnappy>:
   14fb0:       b8 01 00 00 00          mov    $0x1,%eax
   14fb5:       c3                      retq
(this means return true;)

hadoop-2.7.3/lib/native/libhadoop.so.1.0.0:
0000000000014160 <Java_org_apache_hadoop_util_NativeCodeLoader_
buildSupportsSnappy>:
   14160:       31 c0                   xor    %eax,%eax
   14162:       c3                      retq
(this means return false;)

Are Snappy users expected to rebuild libhadoop.so from scratch or is this
an unintentional change in the release process?
