Markus Kemper commented on SQOOP-3025:
--------------------------------------
Hey Ruslan,
Are you able to provide the following:
1. On the host executing the Sqoop CLI command what are your security settings
for [hive conf] and [hadoop conf]
2. Our [sqoop test] appears to be working without error
[hive conf]
$ cat /etc/hive/conf/*.xml | egrep -B 1 -A 1 -i
"security.authentication|hadoop.security.authorization<"
<property>
<name>hadoop.security.authentication</name>
<value>kerberos</value>
<property>
<name>hadoop.security.authorization</name>
<value>true</value>
[hadoop conf]
$ cat /etc/hadoop/conf/*.xml | egrep -B 1 -A 1 -i
"security.authentication|hadoop.security.authorization<"
<property>
<name>hadoop.security.authentication</name>
<value>kerberos</value>
<property>
<name>hadoop.security.authorization</name>
<value>true</value>
[sqoop test]

"select * from t1"
