Flink启动报错：/bin/config.sh: line 32: syntax error near unexpected token

xxx@ssss:/xxx/flink-1.15.2/bin> sh start-cluster.sh 
/xxx/flink-1.15.2/bin/config.sh: line 32: syntax error near unexpected token `<'
/xxx/flink-1.15.2/bin/config.sh: line 32: `    done < <(find "$FLINK_LIB_DIR" ! -type d -name '*.jar' -print0 | sort -z)'

不要使用 sh start-cluster.sh 直接运行
