Todd Lipcon commented on HADOOP-8901:
-------------------------------------
This seems to incorporate HADOOP-6069, which, the first time it was floated,
had some objections. So rather than sneaking that change into this bug fix, we
should have this just be a fix for the cmake regression, and use HADOOP-6069 if
we want to make libz non-dynamic.
> GZip and Snappy support may not work without unversioned libraries

> 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.
> For libz, I believe we should simply link normally against it, rather than
> loading it using {{dlopen}}. It is part of the base Linux install for every
> distribution I'm aware of, so let's not overcomplicate things.
