By error I deleted the folder app-logs in HDFS. After executing spark-submit, I cannot access yarn logs: [centos@eureambarimaster1]$ yarn logs -applicationId application_1525529485402_0019 -> logs1 18/05/06 20:08:14 INFO client.RMProxy: Connecting to ResourceManager at eureambarislave2.local.eurecat.org/192.168.0.15:8050 18/05/06 20:08:14 INFO client.AHSProxy: Connecting to Application History server at eureambarislave1.local.eurecat.org/192.168.0.10:10200
File /app-logs/centos/logs-ifile/application_1525529485402_0019 does not exist. How can I re-create this folder so that the user "centos" can access it?

I had to run this command to adjust permissions: sudo -u hdfs hdfs dfs -chown centos:centos /user After this I was able to run: spark-submit --master yarn --deploy-mode cluster --driver-memory 6g--executor-memory 4g--executor-cores 2--class org.tests.GraphProcessor /path/to/graph.jar

In particular, if I do this way, I get the following error: Exception in thread "main" org.apache.hadoop.security.AccessControlException: Permission denied: user=centos, access=WRITE, inode="/user/centos/.sparkStaging/application_1523903913760_0007":hdfs:hdfs:drwxr-xr-x

If I do this way (with "sudo -u hdfs"), the jar file is invisible for hdfs user (I get an error message)). But if I run without "sudo -u hdfs", then yarn mode cannot be entered. I think that it's the matter of permissions. But it's not clear to me how to solve this issue in a most correct way. Thanks.

I should execute `spark-submit` in the Hadoop cluster created with Ambari. There are 3 instances: 1 master node and 2 executer nodes.
So, I logged in the master node as `centos` user and executed this command:
sudo -u hdfs spark-submit --master yarn --deploy-mode cluster --driver-memory 6g --executor-memory 4g --executor-cores 2 --class org.tests.GraphProcessor graph.jar
But I got the error message that the file graph.jar does not exist. Therefore I tried to copy this file to HDFS as follows: hdfs dfs -put graph.jar /home/hdfs/tmp However, the error is: No such file or directory: `hdfs://eureambarimaster1.local.eurecat.org:8020/home/hdfs/tmp'

Indeed I just changed "eureambarislave1.local.eurecat.org" with "localhost" during the Hive installation process. Hive was installed successfully without any alert. I assume that "localhost" also works fine.

What I did manually is the following:
sudo su - wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm rpm -ivh mysql-community-release-el7-5.noarch.rpm Then I added Hive service using Ambari UI. According to the UI, MySQL Server was successfully installed as one of the steps of Hive installation process. If I would not do the above-mentioned steps, the installation of MySQL server would fail with the message "resource_management.core.exceptions.ExecutionFailed:Execution of '/usr/bin/yum -d 0 -e 0 -y install mysql-community-release' returned 1.Error:Nothing to do". The file "mysql-connector-java.jar" is downloaded fromhttps://dev.mysql.com/downloads/connector/j/5.1.html Then I added it to "/usr/share/java" and executed: # ls -al /usr/share/java/mysql-connector-java.jar # chmod 644 /usr/share/java/mysql-connector-java.jar # ls -l /var/lib/ambari-server/resources/mysql-connector-java.jar # ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar I cannot login to MySQL. I tried to generate password "grep 'A temporary password is generated for root@localhost' /var/log/mysqld.log |tail -1" and then do "/usr/bin/mysql_secure_installation", but I get: ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
