2.7.3 shipped without Snappy support
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?

Thanks for confirming Vinod, I’ll rebuild libhadoop.so myself in the mean time.
This might be something worth calling out in the release notes.

The way we build the bits as part of the release process changed quite a bit during that release so there were some hiccups.
This seems like an oversight, though I tried to build them as close as possible to the releases before 2.7.3. We can fix this for the next releases.
