Hadoop पर स्कूप:NoSuchMethodError:com.google.common.base.Stopwatch.createStarted ()

कुछ और शोध के बाद, मैंने देखा कि Hadoop 2.x क्लासपाथ को ओवरराइड करता है, इसलिए समाधान एक uberjar बनाने के लिए है और हडूप को पास करें।

मैंने इसके बजाय हडूप 260 के लिए विशिष्ट स्कूप जार का उपयोग करने के लिए भी बदल दिया।

इसलिए, मैंने एक pom.xml बनाया है फ़ाइल, maven package चलाया गया उस पर uberjar उत्पन्न करने के लिए:
