通过emr启动配置进行presto配置

Question

我试图通过我们的EMR启动配置JSON部署presto om EMR。我已经决定了这个github issue of presto中建议的配置属性。我在启动配置中添加了以下presto属性

{
    "Classification": "presto-connector-hive",
    "Properties": {
        "hive.metastore.glue.datacatalog.enabled": "true",
        "hive.table-statistics-enabled": "true"
    },
    "Configurations": []
},
{
    "Classification": "presto-config",
    "Properties": {
        "query.max-memory": "150G",
        "query.max-memory-per-node": "20G",
        "query.max-total-memory-per-node": "30G",
        "memory.heap-headroom-per-node": "10G",
        "query.initial-hash-partitions": "15"
    },
    "Configurations": []
}   

已创建EMR群集，但由于以下错误导致presto失败

Answer 1

安装失败，因为

1. 设置数据大小配置属性时，需要使用“GB”（而非“G”）作为单位
2. 您的版本（0.194）不支持您正在设置的某些属性（memory.heap-headroom-per-node或query.max-total-memory-per-node）。
