在使用sparkSQL查詢hive中的資料時候報錯：

java.lang.ClassNotFoundException Class org.apache.hive.hcatalog.data.JsonSerDe not found java.lang.ClassNotFoundException: Class org.apache.hive.hcatalog.data.JsonSerDe not found

hive資料是logservice投遞到oss上的，只使用hive sql的話可以得到資料，資料表結構如下：

CREATE EXTERNAL TABLE `workflow_operation`(

`level` string COMMENT 'from deserializer',

`location` string COMMENT 'from deserializer',

`message` string COMMENT 'from deserializer',

`thread` string COMMENT 'from deserializer',

`time` string COMMENT 'from deserializer')

PARTITIONED BY ( `year` string, `month` string, `day` string, `hour` string)

ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe'

STORED AS INPUTFORMAT 'org.apache.hadoop.mapred.TextInputFormat'

OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'

LOCATION 'oss://weidian-be-production/weidian_be_production/workflow_operation'

TBLPROPERTIES ( 'transient_lastDdlTime'='1535339427')

使用hive sql可以正常查詢，但是使用sparksql：spark-sql -e "use weidian_be_production;set io.compression.codec.snappy.native=true;select * from workflow_operation limit 3;"

會報如上錯誤 另外在hive叢集上已經配置了hive_aux_jars_path=/usr/lib/hive-current/lib/hive-hcatalog-core-2.3.3.jar 但是依然報錯。

解決辦法：把/usr/lib/hive-current/lib/hive-hcatalog-core-2.3.3.jar拷貝到 /usr/lib/spark-current/jars下
