In general, there are no restrictions. You can do whatever you want to with the sandbox. Imaginary is the limit here 😉

@Dominika Bialek How yarn will know when it's the right time to move the workload to the compute nodes? If you keep NodeManager on the DATANODE it's still a WORKER. Also, sending the data to COMPUTE node will impact performance. Is that correct? Is it possible to use a blueprint to crare WASB or ADS as a secendary storage for the cluster? Thanks, ANdrzej

@Sandeep Nemuri I know that apache has it's own repository but I don't understand why hortonworks repo points to the apache rpms...Is that correct? I installed ambari whithin this repo. I got non patched (apache vanilla )ambari. Does the repo contain correct version of ambari? To confirm I run installation once again. Here is ambari version: yum info ambari-server

Hi, I've recently installed cluster (HDP 3.0.1) with ambari 2.7.1.0 and hit the wall of bugs..... I checked release notes of ambari: Ambari-2.7.1.0 and I don't understand which version does include patches? In the release notes there is the following information: "Ambari 2.7.1 is based on Apache Ambari 2.7.1.0 and the following patches." What does it mean? Is there a separate repo for 2.7.1? THanks, ANdrzej

I found an answer on my own. Keyadmin password is set to default '"keyadmin" and can not be overwritten till HDP 3.0 version. If you are using stack < 3.0 you have to change password after deployment of the cluster.

What do you mean by EZK? Encryption Zone key or Enterprise Zone Key? As long as I can generate new keys and created encryption zones everything works fine but is it possible to programmatically determine that Master Key and EZKs are correct? Also, is it possible to encrypt Master Key within Service Master Key and password? Thanks, Andrzej

I have a couple of questions about kms. I went through this article Transparent Data Encryption Explained . We are using HDP 2.6.5 with Ranger and Ranger KMS 0.7. We use postgres as a backend db for keys. 1. As far as I understand only DEK and Master Key are stored in postgres db, correct? 2. I deploy the cluster within Ambari blueprints . How can I verify that master key has been deployed/hashed in a proper way? 3. In terms of backup, do we have to backup either EDEK, EZK keys and postgres db? Or is postgresdb enough? Thanks, Andrzej

I'm trying to deploy kms server within cloudbreak blueprints. I struggle with changing the password for keyadmin: {
"kms-properties" : {
"properties_attributes" : { },
"properties" : {
"KMS_MASTER_KEY_PASSWD" : "super_secure_master_key",
"DB_FLAVOR" : "POSTGRES",
"db_name" : "db_name",
"db_user" : "db_user",
"db_password" : "super_secure_password",
"SQL_CONNECTOR_JAR" : "org.postgresql.Driver",
"REPOSITORY_CONFIG_USERNAME" : "keyadmin",
"REPOSITORY_CONFIG_PASSWORD" : "super_secure_keyadmin_password",
"db_host" : "db_host"
}
}
},<br> After starting the cluster with the procided config the password for keyadmin is still keyadmin..... Is that correct?
Thanks,
Andrzej

Try to remove all cloudera stuff from all nodes (server, agent, daemon) Remove all openjdk packages. Install oracle jdk, e.g. jdk1.8.0_60. Set JAVA_HOME variable. Then install cloudera server on you CM node, run cloudera manager, go to CM settings and set up java_home parameter. After that back to your installation and try to distribute parcels.

I've never seen anything about that in Cloudera documentation. Migrating from one PostgreSQL to MySQL is rather related to db stuff itself. Basic knowledge of PostgreSQL, MySQL and schema could be required.
