---------------------------------------
Summary: DelegationTokenAuthenticationHandler writes via closed
writer
Key: HADOOP-13346
URL: https://issues.apache.org/jira/browse/HADOOP-13346
Project: Hadoop Common
Issue Type: Bug
Components: security
Reporter: Gregory Chanan
Priority: Minor
By default, jackson's ObjectMapper closes the writer after writing, so in the
following code
{code}
ObjectMapper jsonMapper = new ObjectMapper();
jsonMapper.writeValue(writer, map);
writer.write(ENTER);
{code}
(https://github.com/apache/hadoop/blob/8a9d293dd60f6d51e1574e412d40746ba8175fe1/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/security/token/delegation/web/DelegationTokenAuthenticationHandler.java#L280-L282)
writer.write actually writes to a closed stream. This doesn't seem to cause a
problem with the version of jetty that hadoop uses (those just ignore closes),
but causes problems on later verisons of jetty -- I hit this on jetty 8 while
implementing SOLR-9200.
