Arnaud Linz created HADOOP-13186: ------------------------------------ Summary: GenericOptionParser -libjar option validity check not always working because of bad local FS equality check Key: HADOOP-13186 URL: https://issues.apache.org/jira/browse/HADOOP-13186 Project: Hadoop Common Issue Type: Bug Components: util Affects Versions: 2.7.1, 2.6.0 Environment: Occured on: CentOS 6.3 or Ubuntu 14.04, Oracle JDK 1.7.0_45 or 1.8.0_66 Reporter: Arnaud Linz
_Class concerned :_ {{org.apache.hadoop.util.GenericOptionParser}} _Method : _ {{public static URL[] getLibJars(final Configuration conf)}} -Line : _ {{if (tmp.getFileSystem(conf).equals(FileSystem.getLocal(conf))) }} In this method we check if the provided jar on the command line are on a local file system, else we emit a warning log and ignore it. I got the case where the two file systems retrieved (the one from the {{Path.getFileSystem(conf)}} and the one returned by {{FileSystem.getLocal(conf))}} where two local file systems but different objects, and the {{equals()}} method, not having been implemented, defaulted to the object pointer equality, leading to my jar files not being taken into account. I've quickly patched it to {{tmp.getFileSystem(conf).getUri().equals(FileSystem.getLocal(conf).getUri()}} to have my application work. I did not dig further into determining whether the objects should have been the same, or whether the {{equals()}} method should have been implemented, but it has to be done. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
