Subject [jira] [Created] (HADOOP-13346) DelegationTokenAuthenticationHandler writes via closed writer
Date Thu, 07 Jul 2016 00:18:11 GMT
Gregory Chanan created HADOOP-13346:
---------------------------------------

             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.
