---------------------------------
Summary: Print out the file path when the writes on snapshots are
denied
Key: HDFS-10456
URL: https://issues.apache.org/jira/browse/HDFS-10456
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.7.2
Reporter: Tianyin Xu
In {{getINodesInPath4Write}}, the writes on snapshots are denied by throwing
{{SnapshotAccessControlException}}.
Unlike other file operations that print out the file path upon failure,
{{getINodesInPath4Write}} does not.
The attached patch appends the directory path on the logged exception.
{code:title=ViewFs.java|borderStyle=solid}
if (inodesInPath.isSnapshot()) {
throw new SnapshotAccessControlException(
- "Modification on a read-only snapshot is disallowed");
+ "Modification on a read-only snapshot is disallowed: "
+ + inodesInPath.getPath());
}
{code}
