@yassine24,   This shows how to update a service configuration http://cloudera.github.io/cm_api/docs/python-client/#configuring-services-and-roles   You need to update the config with the attribute and value. The configuration is JSON format, but the safety valve you want is in XML format.   An example of how to update a safety valve (hdfs in this case) via REST API is here: curl -iv -X PUT -H "Content-Type:application/json" -H "Accept:application/json" -d '{"items":[{ "name": "core_site_safety_valve","value": "<property><name>hadoop.proxyuser.ztsps.users</name><value>*</value></property><property><name>hadoop.proxyuser.ztsps.groups</name><value>*</value></property>"}]}' http://admin:admin@10.1.0.1:7180/api/v12/clusters/cluster/services/hdfs/config   I am pretty sure you can pass the JSON as shown above in the -d argument hbase.update_config() or whatever ...

Re: Oozie - Create a Spark workflow

The developer (customer side) who work with me on the cluster try to use Apache Airflow, and after one week, he can do what we need (workflow, emailing / alerting, re-run, ...) without the load of files into hdfs, Apache airflow is running in standalone mode and the web UI is better than Oozie UI.   It seems a better solution than oozie, what do you think about this ?   As it is an incubating project, I don't know if it's a good idea, but the web UI is good, it looks easy to manage, I didn't know this new project but I think Oozie is outdated compare to Airflow.   For the moment Oozie is in stand-by, they will make a choice between oozie and airflow, but I must admit that Airflow looks a better solution. ...

Re: Using python to connect to Hive in cloudera

Regarding python 2. If your hive server is configured with SSL, then you should consider installing "sasl" package in python.   As about python3, although this is a python question not hive related, usually the issue is on the previous lines, e.g. quotes or parentheses that do not terminate. ...

Ok, from the log it is obvioues that issue for spark is the old jdk.     When you tried to upgrade java have you defined the java home in "/etc/default/cloudera-scm-server" e.g.: export JAVA_HOME="/usr/lib/jvm/java-8-oracle/" Can you send the relevant "/var/log/cloudera-scm-server/cloudera-scm-server.out" ?   ...

You should not worry for compatibility between KTS and CDH If you check https://www.cloudera.com/documentation/enterprise/latest/topics/encryption_ref_arch.html#concept_npk_rxh_1v CDH connects to KMS. KMS will connect to KTS So you have to check whether the KMS which is compatible to KTS3.8, is compatible with CDH5.14.2.   ... View more
