Colin Patrick McCabe created HDFS-4160:
------------------------------------------
Summary: libhdfs / fuse-dfs should implement O_CREAT | O_EXCL
Key: HDFS-4160
URL: https://issues.apache.org/jira/browse/HDFS-4160
Project: Hadoop HDFS
Issue Type: Improvement
Components: libhdfs
Affects Versions: 2.0.3-alpha
Reporter: Colin Patrick McCabe
Priority: Minor
{{hdfsOpenFile}} contains this code:
{code}
if ((flags & O_CREAT) && (flags & O_EXCL)) {
fprintf(stderr, "WARN: hdfs does not truly support O_CREATE && O_EXCL\n");
}
{code}
But {{hdfsOpenFile}} could easily support *O_CREAT* | *O_EXCL* by calling
{{FileSystem#create}} with {{overwrite = false}}.
We should do this. It would also benefit {{fuse-dfs}}.
