Todd Lipcon created HDFS-3330:
---------------------------------
Summary: If GetImageServlet throws an Error or RTE, response has
HTTP "OK" status
Key: HDFS-3330
URL: https://issues.apache.org/jira/browse/HDFS-3330
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 1.0.0, 2.0.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
Currently in GetImageServlet, we catch Exception but not other Errors or RTEs.
So, if the code ends up throwing one of these exceptions, the
"response.sendError()" code doesn't run, but the finally clause does run. This
results in the servlet returning HTTP 200 OK and an empty response, which
causes the client to think it got a successful image transfer.
