Chris Trezzo commented on MAPREDUCE-6846: ----------------------------------------- Thanks [~jlowe]! I wasn't even thinking about the wildcard parsing from the generic options parser... that will have to change as well. Currently it looks like wildcards are only supported if the path is a directory and the wildcard is at the end of the path (i.e. in the form {{/mydir/*}}). If the wildcard is anywhere else, it is an illegal argument. I can change the parsing of the path so that it handles fragments as well. At that point we can check if the wildcard resolves to multiple jars and throw an exception if there are conflicts as you suggested. That handles the generic options parser part of it. Additionally though, we still have to handle the wildcard portion that handles adding libjars to the distributed cache. Right now, if it is enabled, it will add all libjars in the staging directory using a wildcard (i.e. {{.staging/libjars/*}}) to reduce the size of the jobconf. To handle this part of it, I figure I can go with the approach specified above in #1. If there is a path with a fragment specified we can not use the wildcard feature, otherwise the fragment will not be honored when added to the distributed cache. Let me know if that sounds good! > Fragments specified for libjar paths are not handled correctly > -------------------------------------------------------------- > > Key: MAPREDUCE-6846 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-6846 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 2.7.3, 3.0.0-alpha2 > Reporter: Chris Trezzo > Assignee: Chris Trezzo > Priority: Minor > > If a user specifies a fragment for a libjars path via generic options parser, > the client crashes with a FileNotFoundException: > {noformat} > java.io.FileNotFoundException: File file:/home/mapred/test.txt#testFrag.txt > does not exist > at > org.apache.hadoop.fs.RawLocalFileSystem.deprecatedGetFileStatus(RawLocalFileSystem.java:638) > at > org.apache.hadoop.fs.RawLocalFileSystem.getFileLinkStatusInternal(RawLocalFileSystem.java:864) > at > org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:628) > at > org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:442) > at org.apache.hadoop.fs.FileUtil.copy(FileUtil.java:363) > at org.apache.hadoop.fs.FileUtil.copy(FileUtil.java:314) > at > org.apache.hadoop.mapreduce.JobResourceUploader.copyRemoteFiles(JobResourceUploader.java:387) > at > org.apache.hadoop.mapreduce.JobResourceUploader.uploadLibJars(JobResourceUploader.java:154) > at > org.apache.hadoop.mapreduce.JobResourceUploader.uploadResources(JobResourceUploader.java:105) > at > org.apache.hadoop.mapreduce.JobSubmitter.copyAndConfigureFiles(JobSubmitter.java:102) > at > org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:197) > at org.apache.hadoop.mapreduce.Job$11.run(Job.java:1344) > at org.apache.hadoop.mapreduce.Job$11.run(Job.java:1341) > at java.security.AccessController.doPrivileged(Native Method) > at javax.security.auth.Subject.doAs(Subject.java:422) > at > org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1892) > at org.apache.hadoop.mapreduce.Job.submit(Job.java:1341) > at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1362) > at > org.apache.hadoop.examples.QuasiMonteCarlo.estimatePi(QuasiMonteCarlo.java:306) > at > org.apache.hadoop.examples.QuasiMonteCarlo.run(QuasiMonteCarlo.java:359) > at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:76) > at > org.apache.hadoop.examples.QuasiMonteCarlo.main(QuasiMonteCarlo.java:367) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at > org.apache.hadoop.util.ProgramDriver$ProgramDescription.invoke(ProgramDriver.java:71) > at org.apache.hadoop.util.ProgramDriver.run(ProgramDriver.java:144) > at org.apache.hadoop.examples.ExampleDriver.main(ExampleDriver.java:74) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > at org.apache.hadoop.util.RunJar.run(RunJar.java:239) > at org.apache.hadoop.util.RunJar.main(RunJar.java:153) > {noformat} > This is actually inconsistent with the behavior for files and archives.
