On that host, try running, hdp-select versions hdp-select status Make sure that /usr/hdp/ dir only contains the version folder and current List all symlinks in /usr/hdp/current and make sure they point to the correct location. Note: if some packages are not installed, it is expected to have dead symlinks.

What version of Ambari are you using? Can you check this URI with the exact version, e.g., http://server:8080/views/ADMIN_VIEW/2.2.1.1/INSTANCE/#/ Can you check the API, http://server:8080/api/v1/users ? Any errors in /var/log/ambari-server/ambari-server.log ?

Ambari 2.2 had to change some default configs for YARN in HDP 2.3.4.0 that are not compatible out-of-the-box with HDP 2.3.0.0. You need to change these configs in yarn-site and then restart YARN. yarn.timeline-service.version=1.0 yarn.timeline-service.store-class=org.apache.hadoop.yarn.server.timeline.LeveldbTimelineStore

What's the output of /var/log/hadoop/hdfs/hadoop-hdfs-namenode-pp-hdp-m.log ?

$ grep "password" /etc/ambari-server/conf/ambari.properties server.jdbc.user.passwd=/etc/ambari-server/conf/password.dat $ echo "bigdata_custom" > /etc/ambari-server/conf/password.dat $ sudo -u postgres psql postgres=# ALTER USER ambari WITH PASSWORD 'bigdata_custom'; postgres=# \q $ ambari-server restart

Try just, netstat -tupln | grep -i 10000 Any firewall rules?

Actually, that issue is fixed in Ambari 2.1.2 by https://issues.apache.org/jira/browse/AMBARI-12979

As of HDP 2.2.4, I believe that Knox changed its data folder to be a symlink to a versioned folder, so /usr/hdp/current/knox-server/data -> /var/lib/knox/data/${version} (or something like this) This means that Knox in Ambari should always follow the symlink to get the right path instead of trying to access /var/lib/knox/data directly. I opened AMBARI-14726 to track a fix.

This should be against the requests endpoint, e.g., http://ambariserver:8080/api/v1/clusters/horton/requests

Hi Gerd, can you check the following, rpm -qa | grep hadoop # make sure it is installed and that /etc/hadoop/conf exists ls -la /usr/hdp/current/hadoop-client # should be a symlink to /etc/hadoop/conf, if not, create it
