將Datastax Sqoop遷移問題從sybase遷移到cassandra

Question

我正在使用以下命令將映像數據從Sybase ASE遷移到Datastax cassandra以移動單個表。

sudo ./bin/dse sqoop cql-import --connect 

jdbc:sybase:Tds:XX.XX.XX.XX:XXXXX/db_name?ServiceName=master --username 

user --table TableName --cassandra-username cassandra_username --cassandra- 

password cassandra_password --driver com.sybase.jdbc4.jdbc.SybDriver --verbose - 

-cassandra-keyspace DocumentWareHouse --cassandra-table CASS_TABLENAME -- 

cassandra-host XX.XX.XX.XX -P 

下面的錯誤，我現在面臨

Hadoop functionality is deprecated and may be removed in a future release.

它是在錯誤明確提到：

Output directory DispatchDocumentType already exists

刪除這個目錄和嘗試。它應該工作。
