sqoop2 falha ao iniciar

Question

Meu sqoop2 de repente morre e não consigo iniciar desde 2 dias atrás, eu não mudei nenhuma configuração no sqoop2, eu verifiquei o log do / var / log / sqoop2 catalina que ele diz:

Alguém tem alguma ideia? Obrigado!

    

Answer 1

Esta parece ser a parte relevante do registro:

java.net.BindException: Address already in use

A causa mais provável é:

1. O sqoop2 já está em execução (mas em um estado quase morto, não respondendo ou fazendo qualquer coisa útil, mas ainda em execução. Ou seja, travou em vez de travar).

Verifique com ps aux | grep sqoop . Mate-o se estiver em execução e reinicie.

Ou:

2. algo mais está em execução, que está usando a mesma porta. Tente executar netstat -tupan | grep :port (onde "port" é o número da porta que o sqoop2 deseja vincular). Mate-o e inicie o sqoop2.
