Sqoop trên Hadoop:NoSuchMethodError:com.google.common.base.Stopwatch.createStarted ()

Sau một số nghiên cứu sâu hơn, tôi thấy rằng Hadoop 2.x ghi đè classpath, vì vậy giải pháp là tạo một uberjar và chuyển nó cho hadoop.

Tôi cũng đã thay đổi để sử dụng jar sqoop cụ thể cho hadoop260.

Vì vậy, tôi đã tạo một pom.xml tệp, đã chạy maven package trên đó để tạo uberjar:
