This article mainly introduces the use of Sqoop error report how to do the relevant knowledge, the content is detailed and easy to understand, the operation is simple and fast, with a certain reference value, I believe that everyone after reading this Sqoop error report how to do the article will have a harvest, let's take a look at it.

Foreword:

Recently, because I want to use Sqoop to output data to hdfs, but I found that Sqoop1.4.5 is not compatible with hadoop2.X, so I need to compile Sqoop1.4.5. I always have an error every time I execute the $SQOOP_HOME/bin/sqoop script:

Error: Could not find or load main class org.apache.sqoop.Sqoop

This is due to the fact that the sqoop-1.4.5.jar file cannot be found.

Solution:

Modify the $SQOOP_HOME/bin/sqoop script:

* before modification:

Exec ${HADOOP_COMMON_HOME} / bin/hadoop org.apache.sqoop.Sqoop "$@"

* after modification:

Exec ${HADOOP_COMMON_HOME} / bin/hadoop jar $SQOOP_HOME/sqoop-1.4.5.jar org.apache.sqoop.Sqoop "$@"

That is, displays the location of the specified sqoop-1.4.5.jar file.

Then execute the sqoop help command, and the Could not find or load main class org.apache.sqoop.Sqoop error will not be reported again.

Version Notes:

Hadoop version: Hadoop2.4.0

Sqoop version: sqoop-1.4.5.bin__hadoop-2.0.4
