title: emrfs consistent view and command line copy/delete
body: <p>On my cluster, I've enabled emrfs consistent view and it's working fine when running spark jobs.  </p>
  
  <p>However, I find tedious to manually sync/delete/import metadata after generic s3 operations.</p>
  
  <p>For instance, after a copy, s3 becomes inconsistent:</p>
  
  <pre><code>aws s3 cp localfile1 s3://bucket/path/
  emrfs sync s3://bucket/path/
  emrfs diff s3://bucket/path/
  
  BOTH | MANIFEST ONLY | S3 ONLY
  DIR  bucket/path/           (BOTH)
  FILE bucket/path/localfile1 (BOTH)
  </code></pre>
  
  <p>Here, localfile1 and metadata are in sync.</p>
  
  <pre><code>aws s3 cp localfile2 s3://bucket/path/
  emrfs diff s3://bucket/path/
  
  BOTH | MANIFEST ONLY | S3 ONLY
  DIR  bucket/path/           (BOTH)
  FILE bucket/path/localfile1 (BOTH)
  FILE bucket/path/localfile2 (S3 ONLY)
  </code></pre>
  
  <p>Is there a way to keep metadata in sync with s3 when performing operations like that directly from the EMR cluster where consistent view is enabled?</p>
  
  <p>Thanks</p>
