因?yàn)榻ū頃r(shí)使用了 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'，而不是'org.apache.hadoop.hive.serde2.RegexSerDe'，導(dǎo)致在使用spark-sql或者spark-shell訪問(wèn)時(shí)，一直報(bào)上述異常，總是找不到相應(yīng)的類(lèi)，導(dǎo)入相關(guān)的Jar包仍然無(wú)法解決。

解決辦法：

    要啟動(dòng)spark-shell,spark-sql時(shí)導(dǎo)入 --jar xxxxx.jar將相應(yīng)的jar包導(dǎo)入。（注意：正常情況下，大家應(yīng)該都會(huì)想到將相應(yīng)jar導(dǎo)入。但我遇到的問(wèn)題，如果jar的路徑是個(gè)軟連接路徑的話(huà)，仍然會(huì)報(bào)上述異常，找不到相應(yīng)的類(lèi)，必須導(dǎo)入jar包的實(shí)際路徑才行?？赡芤?yàn)閟park對(duì)軟路徑的處理有bug，不確定哦。。。。）
