HDFS Permission

+1 vote

I'm totally new in Hadoop.

One of SAS users has a problem to save a file from SAS Enterprise Guide to Hadoop and I've been asked to check permissions in HDFS that if they have been granted properly. Somehow to make sure users are allowed to move from one side and to add it to the other side. Where should I check for it on SAS servers? If it is a file or how can I check it?

You have to check permissions on the hadoop side for this. You have to know where they are putting the data into hadoop. These are paths in HDFS, not the servers file system.

Hadoop Stickybit enabled by default prevents users from writing to /tmp in HDFS. Some SAS Programs write to /tmp folder in hdfs to save metadata, along with other information.

If your Hadoop cluster is secured using Kerberos then each SAS user much have a valid kerberos ticket to talk to any Hadoop service. There are a number of guides on the SAS Hadoop Support page about Kerberos along with other resources. With kerberos they need a kerberos ticket, not a username or password.
