At first glance, I couldn't find the jar package. This problem had plagued me for one day. It was useless to modify all kinds of lib, and the English materials found on the Internet were useless (the version was too new and there was no Chinese material ). [Pitfalls] solution:
Go to $ SQOOP_HOME/bin and modify the 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/lib/sqoop-1.4.3-cdh4.5.0.jar org. apache. sqoop. Sqoop "$ @"
It can be seen that, because the hadoop command is used, it is required to install hadoop on the machine where the sqoop-1.4.3-cdh4.5.0 is installed first
