问题

I am trying to import data from MySql to HDFS using Sqoop. But I am getting the following error.

How to solve this?

command :

sqoop import --connect jdbc:mysql://localhost/testDB --username root --password password --table student --m 1

error :

 ERROR tool.ImportTool: Encountered IOException running import job: java.io.FileNotFoundException: File does not exist: hdfs://localhost:54310/usr/lib/sqoop/lib/parquet-format-2.0.0.jar

Hadoop version : 2.6.0

Sqoop version : 1.4.6

You can solve this by adding all jars in /usr/local/sqoop/lib into HDFS :

First create a directory in HDFS :

hdfs dfs -mkdir -p /usr/lib/sqoop/lib/

Then put all libraires into HDFS

hdfs dfs -put /usr/lib/sqoop/lib/* /usr/lib/sqoop/lib/

Then check That the jars exists in HDFS :

hdfs dfs -ls /usr/lib/sqoop/lib

Finnaly import data using sqoop :

sqoop import --connect jdbc:mysql://localhost/testDB --username root --password password --table student --m 1
