OK. I didn't realize that I didn't install the latest version. Since my goal is to obtain the HDPCA certificate, I used the reference links from http://hortonworks.com/training/class/hdp-certified-administrator-hdpca-exam/. Unfortunately they are not up to date. I guess I will also be trying the upgrade process then.. 😛

Looking at the command that causes the error: 2016-01-15 15:37:00,440 - Execute['/usr/hdp/current/knox-server/bin/knoxcli.sh create-master --master [PROTECTED]'] {'environment': {'JAVA_HOME': u'/usr/jdk64/jdk1.7.0_67'}, 'not_if': "ambari-sudo.sh su knox -l -s /bin/bash -c 'test -f /var/lib/knox/data/security/master'", 'user': 'knox'} Originates to /var/lib/ambari-agent/cache/common-services/KNOX/0.5.0.2.2/package/scripts/knox.py cmd = format('{knox_client_bin} create-master --master {knox_master_secret!p}')
master_secret_exist = as_user(format('test -f {knox_master_secret_path}'), params.knox_user)
Execute(cmd,user=params.knox_user,environment={'JAVA_HOME': params.java_home},not_if=master_secret_exist,) {knox_master_secret_path} resolves to /var/lib/knox/data/security/master (as defined in /var/lib/ambari-agent/cache/common-services/KNOX/0.5.0.2.2/package/scripts/params_linux.py). The problem is that the Knox master file does not exist on this location. The directory /var/lib/knox/data does exist, but the content is empty. Instead, the master key is located here: /usr/hdp/current/knox-server/data/security/master In the file /var/lib/ambari-agent/cache/common-services/KNOX/0.5.0.2.2/package/scripts/knox_gateway.py, I also see something with removing/setting symbolic links: # Used to setup symlink, needed to update the knox managed symlink, in case of custom locations
if os.path.islink(params.knox_managed_pid_symlink) and os.path.realpath(params.knox_managed_pid_symlink) != params.knox_pid_dir:
os.unlink(params.knox_managed_pid_symlink)
os.symlink(params.knox_pid_dir, params.knox_managed_pid_symlink) Perhaps something goes wrong with the symbolic links? (when you install HDP2.3 successfully, but try to restart all services immediately after the installation?) ---- In any case, the following modification resolved the issue for me.. I'm not sure if it covers everything (e.g. what will happen if you change the Knox master key via the Ambari web interface??), but I don't have any more time to be stuck on this issue 🙂 Open /var/lib/ambari-agent/cache/common-services/KNOX/0.5.0.2.2/package/scripts/params_linux.py Change: knox_master_secret_path = '/var/lib/knox/data/security/master'
knox_cert_store_path = '/var/lib/knox/data/security/keystores/gateway.jks' to: knox_master_secret_path = '/usr/hdp/current/knox-server/data/security/master'
knox_cert_store_path = '/usr/hdp/current/knox-server/data/security/keystores/gateway.jks' Looking forward to a response from a Hortonworks employee..

Installing with Oracle JDK 1.7 instead of JDK 1.8 did not make a difference. Result of Knox gateway start: 2016-01-15 15:37:00,354 - Directory['/var/lib/knox/data'] {'owner': 'knox', 'group': 'knox', 'recursive': True}

Hello, I'm having the exact same issue when installing the latest version of HDP2.3 a couple of hours ago. During the ambari-server setup installation process, I chose to install the Oracle JDK 1.8 (jdk1.8.0_40). Will try the installation again tomorrow from scratch with Oracle JDK 1.7. Cedric
