The "Spring XD" xd-shell can't run the hadoop fs ls command, the command returns a java exception - hadoop

Question

I compiled the latest spring-xd as I needed CDH support. I am able to start the server however when I connect to the server via the xd-shell I try to change a "configuration". Also this is a kerberized cluster, I am not sure how xd will/can handle that.
1st scenario:
admin config server --uri http://testdomain:10111
hadoop config fs --namenode hdfs://nameservice1:8020
hadoop config props set hadoop.security.group.mapping=org.apache.hadoop.security.ShellBasedUnixGroupsMapping
hadoop config props load hadoop.security.group.mapping
hadoop fs ls
Error message:
xd:>hadoop fs ls
-ls: Fatal internal error

2nd scenario
alternatively I remove some java opts
run steps 1, 2 from previous scenario
then
hadoop config props set hadoop.security.authorization=true
hadoop config props set hadoop.security.authentication=kerberos
error below
16:50:29,682 WARN Spring Shell util.NativeCodeLoader:62 - Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
ls: Authorization (hadoop.security.authorization) is enabled but authentication (hadoop.security.authentication) is configured as simple. Please configure another method like kerberos or digest.
Thanks for you assistance - can't wait to get this working!

Answer 1

Thanks for raising this - we haven't tested with authorization/authentication in the shell for a while - though it is tested as part of the project https://github.com/vmware-serengeti/serengeti-ws
Are you able to perform operations using the standard hadoop file system shell. e.g.
hdfs dfs -ls /user/hadoop/file1

Answer 2

There is currently no specific support in XD for running against a secured Hadoop cluster.
Feel free to open a JIRA ticket at https://jira.springsource.org/browse/XD -- this is something we know we will have to address soon.
