Subject Re: can we use -libjars with the Sqoop tool?
Date Thu, 06 Jun 2013 12:56:18 GMT
i am running the Sqoop tool as follows.


hadoop --config path/to/sqoop-cluster-config-dir jar sqoop-1.4.3.jar
org.apache.sqoop.Sqoop import -libjars ${LIBJARS} --connect
jdbc:mysql://mysql/mydb --username myuser --password mypass --table data
--verbose --append --warehouse-dir /sqoop

i am getting this stack trace.

java.lang.RuntimeException: java.lang.ClassNotFoundException:
        at org.apache.hadoop.mapred.Task.initialize(Task.java:501)
        at org.apache.hadoop.mapred.MapTask.run(MapTask.java:306)

        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)

when i looked at the sqoop-1.4.3.jar, clearly,
org.apache.sqoop.mapreduce.RawKeyTextOutputFormat.class exists.

any ideas what's going on?
