Colin Patrick McCabe updated HADOOP-8806:
-----------------------------------------
Description:
libhadoop calls {{dlopen}} to load {{libsnappy.so}} and {{libz.so}}. These
libraries can be bundled in the {{$HADOOP_ROOT/lib/native}} directory. For
example, the {{-Dbundle.snappy}} build option copies {{libsnappy.so}} to this
directory. However, snappy can't be loaded from this directory unless
{{LD_LIBRARY_PATH}} is set to include this directory.
Can we make this configuration "just work" without needing to rely on
{{LD_LIBRARY_PATH}}?

Should we also search {{java.library.path}} when loading these libraries?
Summary: libhadoop.so: dlopen should be better at locating
libsnappy.so, etc. (was: libhadoop.so: search java.library.path when calling
dlopen)
> libhadoop.so: dlopen should be better at locating libsnappy.so, etc.
