When using the HADOOP procedure or a LIBNAME statement with the Hadoop engine to write data to Hadoop, you might get the following Kerberos error:

Symptoms

When making a LIBNAME connection to Hadoop, you might get an error that the LIBNAME statement did not assign successfully: 

To check the permission on the HDFS_TEMPDIR directory, you can try writing to HDFS by using PROC HADOOP, which results in the following error: 

Similarly, the LIBNAME statement might assign successfully without the HDFS_TEMPDIR option. But, when trying to write data to HDFS, you get the same error:

Cause

This is not actually a Kerberos issue as indicated by the error. The LIBNAME statement should assign correctly without using the HDFS_TEMPDIR option and be able to read data from Hadoop. The error occurs only when you try to write data. 

The issue appears to be a Java classpath issue with some releases of Hadoop.

Workaround

 To work around this issue, make a copy of the core-site.xml and move it into the SAS_HADOOP_JAR_PATH directory.
