Hans Uhlig created HDFS-4220:
--------------------------------
Summary: Augment AccessControlException to include both affected
inode and attempted operation
Key: HDFS-4220
URL: https://issues.apache.org/jira/browse/HDFS-4220
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs client, name-node
Affects Versions: 2.0.2-alpha
Reporter: Hans Uhlig
Priority: Minor
Currently when any application that uses hdfs runs and hits a permissions wall
a message similar to the following is emitted.
FAILED: RuntimeException org.apache.hadoop.security.AccessControlException:
Permission denied: user=huhlig, access=WRITE, inode="/":hdfs:hadoop:drwxr-xr-x
This provides a bit of information including who, did what and where but not
what I tried to do. This makes debugging naughty or misconfigured applications
difficult to debug.
A preferable addition to this would follow inode
FAILED: RuntimeException org.apache.hadoop.security.AccessControlException:
Permission denied: user=huhlig, access=WRITE, inode="/":hdfs:hadoop:drwxr-xr-x,
operation=mkdir:"/new/path/to/make"
This would allow for easier tracing of applications like hive where they may
hit odd file system spaces.
