SQOOP Not able to import table

Question

I am running below command on sqoop

sqoop import --connect jdbc:mysql://localhost/hadoopguide --table widgets

my version of sqoop : Sqoop 1.4.4.2.0.6.1-101
Hadoop -- Hadoop 2.2.0.2.0.6.0-101

Both taken from hortonworks distribution. all the paths like HADOOP_HOME, HCAT_HOME, SQOOP_HOME are set properly. I am able to get list of databases, list of tables from mysql database by running list-database, list-tables commands in sqoop. Even able to get data from --query 'select * from widgets'; but when i use --table option getting below error.

Specify the --bindir where the compiled code and .jar file should be located.

Without these arguments, Sqoop would place the generated Java source file in your current working directory and the compiled .class file and .jar file in /tmp/sqoop-<username>/compile.
