Elasticsearch 5.1.1 与 repository hdfs 集成启动出错

[111145 (张宇鹏)]

已经下载好了 repository hdfs ，但配置 elasticsearch.yml 出错，不能识别 hdfs 属性。

下面是我的 elasticsearch.yml 配置内容
repositories:
hdfs:
uri: "hdfs://es-master:9000/" # optional - Hadoop file-system URI
path: "some/path" # required - path with the file-system where data is stored/loaded

load_defaults: "true" # optional - whether to load the default Hadoop configuration (default) or not

conf_location: "/home/yuppy/hadoop-2.6.5/etc/hadoop/core-site.xml,/home/yuppy/hadoop-2.6.5/etc/hadoop/hdfs-site.xml" # optional - Hadoop configuration XML to be loaded (use commas for multi values)

conf. : "" # optional - 'inlined' key=value added to the Hadoop configuration

concurrent_streams: 5 # optional - the number of concurrent streams (defaults to 5)

compress: "false" # optional - whether to compress the metadata or not (default)

chunk_size: "10mb" # optional - chunk size (disabled by default)

不知道有没有注意 yml 文件的格式，另外还能通过 restful 的方式来进行配置:
PUT _snapshot/my_hdfs_repository
{
"type": "hdfs",
"settings": {
"uri": "hdfs://namenode:8020/",
"path": "elasticsearch/respositories/my_hdfs_repository",
"conf.dfs.client.read.shortcircuit": "true"
}
}
