> libsnappy loader issues
> -----------------------
>
> Key: HADOOP-8756
> URL: https://issues.apache.org/jira/browse/HADOOP-8756
> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.2.0-alpha
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Attachments: HADOOP-8756.002.patch

> We use {{System.loadLibrary("snappy")}} from the Java side. However in
> libhadoop, we use {{dlopen}} to open libsnappy.so dynamically.
> System.loadLibrary uses {{java.library.path}} to resolve libraries, and
> {{dlopen}} uses {{LD_LIBRARY_PATH}} and the system paths to resolve
> libraries. Because of this, the two library loading functions can be at odds.
> We should fix this so we only load the library once, preferably using the
> standard Java {{java.library.path}}.
> We should also log the search path(s) we use for {{libsnappy.so}} when
> loading fails, so that it's easier to diagnose configuration issues.
