Kihwal Lee commented on HDFS-13306: ----------------------------------- {{HttpFSServerWebApp}} implements {{ServerWebApp}}, which blows up with an {{IllegalArgumentException}} if "NAME.home.dir" is not set. When it is initialized through jersey, it must be swallowing the runtime exception, causing no instance to be created. > NullPoint when launch org.apache.hadoop.fs.http.server.HttpFSServerWebServer > ---------------------------------------------------------------------------- > > Key: HDFS-13306 > URL: https://issues.apache.org/jira/browse/HDFS-13306 > Project: Hadoop HDFS > Issue Type: Bug > Components: fs > Reporter: lqjacklee > Priority: Critical > > org.apache.hadoop.fs.http.server.HttpFSServerWebServer > objc[98322]: Class JavaLaunchHelper is implemented in both > /Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/bin/java > (0x10a41b4c0) and > /Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/jre/lib/libinstrument.dylib > (0x10a49f4e0).
