Sqoop Error, Sqoop 2 not working through hue

Contributor

Hello,

 

We have installed CDH 5.3 on 20 nodes, which comes with both sqoop 1 and sqoop2.

 

I am trying to run a sqoop 1 job through command line interactive shell, but unable to as it throws execption. As I change the jar, the error differs.

 

DB: postgresql

 

I have kept the jar file for postgresql inside /var/lib/sqoop/

 

I tried to give all required permissions on the sqoop, but still unable to run it.

 

It says no db jar selected or read.

 

When I try to use sqoop 2 through Hue, It doesnot allow me to create sqoop job, it is like when you click on create new job, it does not go to next page.

Hello abe,

 

Thanks for helping me, the issue has been resolved bby itself, do not know what happened, I felt there some kind of special characters auto generated on top of the directory name, hence it was saying no such file or directory, as soon as I deleted the directory and created the new one, it works fine.

Sqoop2 is going throgh a lot of changes and isn't supported in Hue in CDH 5.3.0. It should be in CDH 5.3.2 AFAIK.

 

The Sqoop1 command you are running have two different problems:

  1. The postgresql jdbc driver jar isn't available on one of your nodes. This can be fixed by downloading it and putting it in /var/lib/sqoop.
  2. The problem seems to be some kind of SQL error. Could you add --verbose to your sqoop command? sqoop import --verbose ...

Hi abe,

 

I am getting new issue on hdfs,

 

sqoop is running fine and it creates an output directory on the given --target-dir path /xxx.........but the issue is I can see the directory on hdfs, but cannot access, when given hadoop fs -ls /xxx , it says no such file or directory.....Pls help me to resolve this issue 

Re: Sqoop Error, Sqoop 2 not working through hue

Also when I tried to access it through Hue.....It says following

 

 

You are a Hue admin but not a HDFS superuser (which is "hdfs").

Re: Sqoop Error, Sqoop 2 not working through hue

It seems like the job didn't run. Are you sure it finished? There should be task logs associated with your job. Could you check them for errors? Also, make sure --verbose is in your command for the best possible debug information.

Re: Sqoop Error, Sqoop 2 not working through hue

Contributor

Yes, the Job run successfully, but still I am unable to view the file as the directory which has it, doesnot open.......

 

sqoop ran successfully and retrieved 4 records, and also created the directory by itself when I specify explecitly from command line,

 

It is not allowing me to look into direcctory.......it says no such file or directory, but I can notice that it is present......something to do with permissions for hdfs??

Re: Sqoop Error, Sqoop 2 not working through hue

Expert Contributor

From the CLI, Hadoop normally shows: "ls: Permission denied: user=admin..." if you don't have permission. What is your --target-dir set to?

Re: Sqoop Error, Sqoop 2 not working through hue

Contributor

You are right it should say permission denied, but strangely it says "No file or directory found" , but we can see that directory is present.....
