The method addCacheFIle(URI) is undefined for the type Job

 Hi,
I encountered an error that I cannot understand.

Configuration conf = new Configuration();
Job job = new Job(conf, "job1");
job.addCacheFile(new URI(args[0]));

Why did it report "The method addCacheFile(URI) is undefined for the type Job"?
Thanks!

Doesn't look like it to me:

Joey Echeverria,
Yes, that works.
I thought job.addCacheFile(new URI(args[0])); could run on hadoop-0.20.2.
Because hadoop-0.20.2 could run context object.
Thanks!

I think the API call you're looking for is
DistributedCache.addCacheFile(URI, Configuration) [1]

Harsh,
It is java.net.URI that is imported.

Jun,

Common cause is that your URI class is not the right import.

It must be java.net.URI and not any other class. Fix this and your
problem would go away.
