從java中的csv將數據導入快照數據時出錯

Question

我在scala中的表架構是

snSession.sql（“ create table category_subscriber（id int，catId int，brandId int，domains int，osId int，rType int，rTime int，ctId int，icmpId int，setId int，rAt int，cyId int）使用欄選項（BUCKETS '5'，PARTITION_BY'ID'，OVERFLOW'true'，EVICTION_BY'LRUHEAPPERCENT'）“）;

我在Java中的代碼是

Statement statement = snappy.createStatement();
            statement.execute("CREATE EXTERNAL TABLE CATEGORY_SUBSCRIBER USING com.databricks.spark.csv OPTIONS(path '/home/sys1010/Desktop/category_sub.csv', header 'true', inferSchema 'true', nullValue 'NULL', maxCharsPerColumn '4096';");

通過Java將數據從CSV導入到snappydata時出現錯誤

CSV中的數據由制表符空間分隔，就像

59314315    22  0   50  0   4   1531506600  0   87152   0   1531582029  0   2018-07-31

有人可以幫我嗎

Answer 1

該語句中有語法錯誤，更正后的語句是：

語句語句= snappy.createStatement（）; statement.execute（“使用com.databricks.spark.csv選項創建外部表CATEGORY_SUBSCRIBER（路徑'/home/sys1010/Desktop/category_sub.csv'，標頭'true'，inferSchema'true'，nullValue'NULL'，maxCharsPerColumn' 4096'）“）;

Answer 2

使用CSV選項（....）創建外部表<name>也應該起作用。 CSV現在是內置數據源。
