Spyrk-cluster is a data mini-lab, considering the main technologies used these days. It's useful to either understand how to configure a cluster, or just to take it for granted to use for testing with submit or interactive jobs.

spyrk-cluster's Issues

Suporte ao Hive

Adicionar suporte ao Hive, de maneira que se possa utiliza-lo para testes nas transformações de dados no cluster simulado.

MapReduce não funciona depois de se abrir uma SparkSession no Jupyter

O problema persiste mesmo quando se executa spark.stop(). Ao se gerar tabelas do hive via spark-submit, e se gerar um job MapReduce (i.e. fazendo SELECT COUNT(*) [...]), é possível verificar a finalização do processo.

Ao se gerar tabelas via sessão interativa, verifica-se o erro.

Possibilidades: algum problema ao se interagir do modo interativo junto ao modo cluster; ou algum problema de alocação de recursos nos arquivos yarn-site.xml ou mapred-site.xml
