Las tablas Hive no se encuentran cuando se ejecuta en modo YARN-Cluster

Question

Tengo una aplicación Spark (versión 1.4.1) en HDP 2.3. Funciona bien cuando se ejecuta en el modo YARN-Client. Sin embargo, al ejecutarlo en modo YARN-Cluster, la aplicación no puede encontrar ninguna de mis tablas Hive.

Presento la solicitud así:

./bin/spark-submit 
    --class com.myCompany.Main 
    --master yarn-cluster 
    --num-executors 3 
    --driver-memory 4g 
    --executor-memory 10g 
    --executor-cores 1 
    --jars lib/datanucleus-api-jdo-3.2.6.jar,lib/datanucleus-rdbms-3.2.9.jar,lib/datanucleus-core-3.2.10.jar /home/spark/apps/YarnClusterTest.jar  
    --files /etc/hive/conf/hive-site.xml

Aquí hay un extracto de los registros:

Básicamente me encuentro con el mismo problema de "no hay tal mesa" en cualquier momento en que mi aplicación necesite leer o escribir en las tablas de Hive.

Answer 1

Si puede obtener datos usando Hive CLI, entonces use el mismo hive-site.xml en su trabajo Spark.

La única razón podría ser la ubicación del metastore definido en hive-site.xml.

Answer 2

Publiqué esta misma pregunta en la comunidad de Hortonworks y resolví el problema con la ayuda de esta respuesta.

La esencia de esto es esta: al enviar la aplicación, el argumento --files debe venir antes del argumento --jars , y la copia de hive-site.xml para usar es la del directorio de chispa de chispa, no en $HIVE_HOME/conf/hive-site.xml . Por lo tanto:

  ./bin/spark-submit /
  --class com.myCompany.Main /
  --master yarn-cluster /
  --num-executors 3 /
  --driver-memory 1g /
  --executor-memory 11g /
  --executor-cores 1 /
  --files /usr/hdp/current/spark-client/conf/hive-site.xml /
  --jars lib/datanucleus-api-jdo-3.2.6.jar,lib/datanucleus-rdbms-3.2.9.jar,lib/datanucleus-core-3.2.10.jar /
  /home/spark/apps/YarnClusterTest.jar
