Charles Lamb commented on HDFS-7067: ------------------------------------ The three FB warnings appear to be unrelated. I ran FB with and without the patch and it produced the same results. The test failure is expected since test-patch does not apply the hdfs7067.keystore file to src/test/resources. Code Warning RV Return value of java.util.concurrent.CountDownLatch.await(long, TimeUnit) ignored in org.apache.hadoop.ha.ActiveStandbyElector$WatcherWithClientRef.process(WatchedEvent) Multithreaded correctness Warnings Code Warning AT Sequence of calls to java.util.concurrent.ConcurrentHashMap may not be atomic in org.apache.hadoop.net.NetUtils.canonicalizeHost(String) Security Warnings Code Warning XSS HTTP parameter written to Servlet output in org.apache.hadoop.jmx.JMXJsonServlet.doGet(HttpServletRequest, HttpServletResponse) > ClassCastException while using a key created by keytool to create encryption > zone. > ----------------------------------------------------------------------------------- > > Key: HDFS-7067 > URL: https://issues.apache.org/jira/browse/HDFS-7067 > Project: Hadoop HDFS > Issue Type: Bug > Components: encryption > Affects Versions: 2.6.0 > Reporter: Yi Yao > Assignee: Charles Lamb > Priority: Minor > Attachments: HDFS-7067.001.patch, HDFS-7067.002.patch, > hdfs7067.keystore > > > I'm using transparent encryption.

I know > we should use 'hadoop key create' to create a key.
