---------------------------------------
Attachment: HDFS-3808.001.patch
> 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
> Attachments: HDFS-3808.001.patch
>
>
> {{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.
