Ahmed Radwan commented on HADOOP-8756: -------------------------------------- The TestZKFailoverController failures seems unrelated (see HADOOP-8591). > 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: 2.0.2-alpha > Reporter: Colin Patrick McCabe > Assignee: Colin Patrick McCabe > Priority: Minor > Attachments: HADOOP-8756.002.patch, HADOOP-8756.003.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. -- This message is automatically generated by JIRA.
