> Key: HDFS-9268
> URL: https://issues.apache.org/jira/browse/HDFS-9268
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Wei-Chiu Chuang
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Attachments: HDFS-9268.001.patch, HDFS-9268.002.patch
>
>
> JVM crashes when users attempt to use vi to update a file on fuse file system
> with insufficient permission. (I use CDH's hadoop-fuse-dfs wrapper script to
> generate the bug, but the same bug is reproducible in trunk)
> The root cause is a segfault in a dfs-fuse method
> To reproduce it do as follows:
> mkdir /mnt/fuse
> chmod 777 /mnt/fuse
> ulimit -c unlimited # to enable coredump
> hadoop-fuse-dfs -odebug hdfs://localhost:9000/fuse /mnt/fuse
> touch /mnt/fuse/y
> chmod 600 /mnt/fuse/y
> vim /mnt/fuse/y
> (in vim, :w to save the file)
> #
