Subject [jira] [Created] (HDFS-3808) fuse_dfs: postpone libhdfs intialization until after fork
Date Wed, 15 Aug 2012 23:04:37 GMT
Colin Patrick McCabe created HDFS-3808:

             Summary: fuse_dfs: postpone libhdfs intialization until after fork
                 Key: HDFS-3808
                 URL: https://issues.apache.org/jira/browse/HDFS-3808
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: fuse-dfs
    Affects Versions: 2.2.0-alpha
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe

{{libhdfs}} may create threads or initialize internal JNI data structures when it is used.
 So we should not call fork() after the library is first used.

Unfortunately, fuse_dfs is doing just this-- initializing libhdfs in its {{main}} function,
prior to calling {{fuse_main}} which does a {{daemonize}} (which involves forking.)  We should
correct this.
