Yes, sure. Sorry, I was actually referring to "hdfs://eureambarimaster1.local.eurecat.org:8020/user/hdfs/test/df.parquet" Let me test it.

I think that this is the reason. If I login as HDFS user and run "hdfs dfs -chown -R centos /home/centos/test", then it says that this directory does not exist. I created this directory as HDFS user and then changed permissions to centos. Should I write a parquet file to the full path?: df.coalesce(1).write.format("parquet").save("hdfs://eureambarimaster1.local.eurecat.org:8020/user/hdfs/test")

Maybe the problem is that I run Spark program in Yarn cluster mode? It means that the driver can be running in any of the machines of the cluster. So, probably I should run "chown -R centos:centos ..." in each machine or do ".coalesce(1)"?

I want to save DataFrame on disk: df.write.format("parquet").save("/home/centos/test/df.parquet") I get the following error, which says that the user "centos" does not have write permissions: 18/05/07 09:18:08 ERROR ApplicationMaster: User class threw exception: org.apache.hadoop.security.AccessControlException: Permission denied: user=centos, access=WRITE, inode="/home/centos/test/df.parquet/_temporary/0":hdfs:hdfs:drwxr-xr-x This is how I run spark-submit command: spark-submit --master yarn --deploy-mode cluster --driver-memory 6g --executor-cores 2 --num-executors 2 --executor-memory 4g --class org.test.MyProcessor mytest.jar

I re-submitted Spark job and now it works fine. The problem was that I submitted Spark job before changing permissions.
