I enabled the log4j.logger.org.apache.http.wire=DEBUG, but it seems that something wrote into the gateway.log and gateway-audit.log only when I am starting the knox service in Ambari. Anyway, I attached the log files, please have a look on them. I tried with the command: curl -ik -u guest:guest-password -H "Accept: text/xml" -X GET 'https://localhost:8443/gateway/sandbox/hbase', but the result is same. There is no default.xml in topology folder. I manually make a copy from sandbox.xml, and try again with "default" in the curl command, the result is same. I paste the sandbox-version output as below: Sandbox information: Created on: 25_10_2016_08_11_26 for Hadoop stack version: Hadoop 2.7.3.2.5.0.0-1245 Ambari Version: 2.4.0.0-1225 Ambari Hash: 59175b7aa1ddb74b85551c632e3ce42fed8f0c85 Ambari build: Release : 1225 Java version: 1.8.0_111 OS Version: CentOS release 6.8 (Final) I just import the sandbox vm, and power it. Then I start HBase service, Knox service, turn off the maintenance mode on them and start Demo LDAP. Then try the curl command, and meet the issue. Did I miss something need to do? Thanks. ...

There is no output to /var/log/knox/gateway.log file when executing the problem curl command. And in I checked the HBase URL in /usr/hdp/2.5.0.0-1245/etc/knox/conf/topologies/sandbox.xml, it seems right. In file, it contains the following entry: <service> <role>WEBHBASE</role> <url>http://localhost:60080</url> </service> Did I check with right files? Thanks for your reply. ... View more
