Ok we have resolved our issues, it was a combination of three things; @antin leszczyszyn and @Artem Ervits put me on the right road, I will document how we solved the issues in the hopes that it helps someone else. 1. As Antin pointed out we had a user issue our group had installed apache ranger which changed the hadoop users and permissions. 2. As Artem pointed out in the link to his tutorial we needed to create a lib folder in the folder that we are running our workflow from and add the jdbc.jar file and add the hive-site.xml and tez-site.xml . 3. When trying to trouble shoot this problem we had changed the scheduler to the fair version, we changed it back to capacity scheduler and changed maximum-am-resource-percent=0.2 to 0.6 Thanks for the help

@Artem Ervits Thanks for pointing to your article it had some good info in it, but still no luck for me. After I uploaded the files and add them to the workflow.xml the only difference I see is I am using sqlserver jdbc driver.

No luck yet. You are correct that I am running the sqoop import form the command line as the hdfs user. Thanks for pointing out the realUser=oozie setting in the logs when I searched the logs I always looked for user and it always said hdfs The first thing I tried was:
hadoop fs -chmod -R 777 /apps/hive/warehouse/perl3.db I also tried adding these properties in my work flow to force oozie to exe as hdfs user, hadoopUser was set in the job file as hdfs
<property> <name>HADOOP_USER_NAME</name> <value>${hadoopUser}</value> </property> <property> <name>hadoop.proxyuser.oozie.hosts</name> <value>hadoopctrl,hadoopm1,hadoopm2,hadoopm3</value> </property> <property> <name>hadoop.proxyuser.oozie.groups</name> <value>hdfs</value> </property> same result with the job in yarn being stuck at 95%

Thanks for taking the time to respond, (little bit of a hadoop noob ) I produced this log by running the command ~$ yarn job -list taking the ID I found there and running this command ~$ yarn logs -applicationId application_1503692663931_0004 > wflog.log The file that was produced was around 5000 lines this seems excessive to me, if there is a better way please let me know. I attached the log file. I trimmed the LogType:directory.info to get the file size down. Thnaks

I have a sqoop import that works fine via the command line ~$ sqoop import --connect "jdbc:sqlserver://10.100.197.46:1433;database=rtoISONE" --username hadoop --password XXXXXX --hive-import --hive-database pe rl3 --hive-overwrite -m 1 --table MaxIndex but when when I try to run it with a oozie workflow it never leaves the RUNNING phase and when I look at it in yarn it sits at 95%, I know that my oozie is set up correctly for one thing because when I run a shell script under it, it completes with out problem. workflow.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?>

<property>
