私は Hadoop ハイブを初めて使用します。ハイブ テーブル上に 1 対 1 のハイブ ビューを作成しようとしましたが、不明なホスト例外が発生します :(

  1. 以下は、テーブルの DDL です。

    CREATE TABLE CLIAMS (
CLAIM_KEY INT,
CLAIM_NAME STRING
)STORED AS SEQUENCEFILE;

  2. ビューの定義は次のとおりです。

    create view claimant_view as select * from claims;

  3. ビューから選択すると、次の例外がスローされます。

    select * from claimant_view;
Total MapReduce jobs = 1
