In fsck, HttpServletResponse sendError fails with IllegalStateException
-----------------------------------------------------------------------
Key: HADOOP-4530
URL: https://issues.apache.org/jira/browse/HADOOP-4530
Project: Hadoop Core
Issue Type: Bug
Components: dfs
Affects Versions: 0.18.1
Reporter: Koji Noguchi
When looking at HADOOP-4526, I tried using sendError at line:53.
{code:title=FsckServlet.java|borderStyle=solid} _
49 } catch (IOException ie) {
50 StringUtils.stringifyException(ie);
51 LOG.warn(ie);
52 String errMsg = "Fsck on path " + pmap.get("path") + " failed.";
53 response.sendError(HttpServletResponse.SC_GONE, errMsg);
54 throw ie;
55 }
{code}
However, it always failed with
{noformat}
