Radim Kolar commented on HADOOP-8901:
-------------------------------------
This fixes zlib on BSD but its still not enough to fix libsnappy. i could not
determine why libsnappy is broken because version
d2b46d18183ad70c0aad5ce278f49fbd52c88a08 works fine.

on freebsd libsnappy is in /usr/local/lib and it has version 2

> Key: HADOOP-8901
> URL: https://issues.apache.org/jira/browse/HADOOP-8901
> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.0.3-alpha
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Fix For: 3.0.0, 2.0.3-alpha
>
> Attachments: HADOOP-8901.001.patch, HADOOP-8901.002.patch,
> HADOOP-8901.003.patch
>
>
> Currently, we use {{dlopen}} to open {{libz.so}} and {{libsnappy.so}}, to get
> Gzip and Snappy support, respectively.
> However, this is not correct; we should be dlopening {{libsnappy.so.1}}
> instead. The versionless form of the shared library is not commonly
> installed except by development packages. Also, we may run into subtle
> compatibility problems if a new version of libsnappy comes out.
> Thanks to Brandon Vargo for reporting this bug.
