Permission exception for Sqoop

Permission exception for Sqoop

Expert Contributor

Stack : Installed HDP-2.3.2.0-2950 using Ambari 2.1

The installation was auto. as the machines(total 9 nodes) had Internet connectivity and was done using root credentials.

An ls command output for reference(sqoop user IS missing) :

[root@l1031lab ~]# hadoop fs -ls /user
Found 7 items
drwx------   - accumulo  hdfs          0 2015-11-05 14:03 /user/accumulo
drwxrwx---   - ambari-qa hdfs          0 2015-10-30 16:08 /user/ambari-qa
drwxr-xr-x   - hcat      hdfs          0 2015-10-30 16:17 /user/hcat
drwxr-xr-x   - hdfs      hdfs          0 2015-11-11 10:09 /user/hdfs
drwx------   - hive      hdfs          0 2015-11-06 09:42 /user/hive
drwxrwxr-x   - oozie     hdfs          0 2015-11-05 12:53 /user/oozie
drwxrwxr-x   - spark     hdfs          0 2015-11-05 13:59 /user/spark
[root@l1031lab ~]#
[root@l1031lab ~]#

Another worrisome(sqoop user IS missing) output when I thought about the user groups :

cat /etc/group

I have the following questions :

  1. Why the error in spite of an auto. installation i.e I didn't skip any services/configurations
  2. How do I proceed
