Sqoop Oracle Import erstellt keine Tabelle

Question

Ich möchte Daten aus einer Oracle-Datenbank in Hive mit Sqoop importieren. Ich möchte, dass Sqoop die Tabelle in die Ziel-Hive-Datenbank erstellt.

Ich legte die Oracle JDBC (ojdbc6.jar) in das Sqoop-Verzeichnis lib.

Ich versuche diese 2 Methoden, aber keine von ihnen funktioniert.

sqoop import \ 
    --connect jdbc:oracle:thin:@${DB_HOST}:${DB_PORT}:${DB_NAME} \ 
    --username ${DB_USER} \ 
    --password ${DB_PWD} \ 
    --table ${INPUT_TABLE} \ 
    --hcatalog-home /usr/hdp/current/hive-webhcat \ 
    --hcatalog-database ${OUTPUT_DB} \ 
    --hcatalog-table ${OUTPUT_TABLE} \ 
    --create-hcatalog-table \ 
    --num-mappers 1 


sqoop import \ 
    --connect jdbc:oracle:thin:@${DB_HOST}:${DB_PORT}:${DB_NAME} \ 
    --username ${DB_USER} \ 
    --password ${DB_PWD} \ 
    --hive-home /usr/hdp/current/hive \ 
    --hive-import \ 
    --create-hive-table \ 
    --hive-table "${OUTPUT_DB}.${OUTPUT_TABLE}" \ 
    --table ${INPUT_TABLE} 

Ich habe diese Fehlermeldung:

ERROR tool.ImportTool: Imported Failed: There is no column found in the target table input_table. Please ensure that your table name is correct.

Es scheint Sqoop nicht berücksichtigt nicht die --create-hcatalog-Tabelle oder --create-Nest-Tabelle

jedoch Wenn ich Daten aus PostgreSQL mit Sqoop importiere, funktioniert die Tabellenerstellung gut. Irgendwelche Ideen? Danke

Zur Information lesen Sqoop gut die Oracle-Tabelle. Ich lief diesen Befehl und bekam das gute Ergebnis:

sqoop eval \ 
    --connect jdbc:oracle:thin:@${DB_HOST}:${DB_PORT}:${DB_NAME} \ 
    --username ${DB_USER} \ 
    --password ${DB_PWD} \ 
    --query "select count(1) from input_table"

Answer 1

ich eine Lösung gefunden, wie es scheint, dass der --table Parameter nicht gut funktionierte für Ich, also habe ich --query Parameter stattdessen verwendet.

sqoop import \ 
     --connect ${DB_CNX_STR} \ 
     --username ${DB_USER} \ 
     --password ${DB_PWD} \ 
     --query "SELECT * FROM ${INPUT_TABLE} WHERE \$CONDITIONS" \ 
     --target-dir ${TARGET_DIR}/${INPUT_TABLE} \ 
     --hive-import \ 
     --hive-home "/usr/hdp/current/hive" \ 
     --create-hive-table \ 
     --hive-table "${OUTPUT_DB}.${OUTPUT_TABLE}" \ 
     --num-mappers 1
