Apache Nifi : using Sqoop export command in execute processor ,will it work?

[#1]

I have configured an Execute Processor with the below :

configuration being :
1.command = /home/hadoop/software/sqoop-1.4.6.bin__hadoop-0.23/bin/sqoop-export
giving the path till sqoop-export file
2.Command Arguments = --connect jdbc:mysql://localhost/test --username root --password root --table test --export-dir /home/hadoop/input.csv

using mysql DB

Sqoop execution begins ,but i see the below error in

nifi logs :SplitAvro : IO Exception : Not a data file

hadoop name node logs :Permission denied: user=root, access=WRITE, inode="/user":hdfs:supergroup:dr

Has anyone tried using sqoop via nifi ?

@manisha jain

It looks like you are running the command with the root user for which it is checking for the home directory availability for this user (root) under HDFS.

The error: Permission denied: user=root, access=WRITE, inode="/user":hdfs:supergroup:dr signifies that it it trying to access the /user directory with the access permission as WRITE for which your user doesn't have access, you can solve this in two ways:

1) run the command with the hdfs user (if you have the permissions)

2) you can get your user created (root in this case) with the required permissions and run the command.

Thanks @Venkata Sudheer Kumar M .You rightly pointed the issue.

Command was executing by default as root user.

Resolution:

I later updated the property under Nifi conf folder in the file bootstrap.conf as below

run.as:hadoop

The command execution was now as hadoop user and it ran successfully.

Sqoop export is invokable via nifi execute processor.
