我尝试将gitlab-CE从10.3.2更新到最新版本（当前为11.4）。它给了我这个诚实安全的错误。

最近一个错误已经出现了，说：Limit of total fields [1000] in index [dev_tweets] has been exceeded。
我想知道是否有人遇到过同样的问题？
另外，如果我运行此curl：
$ curl -s -XGET http://localhost:9200/dev_tweets/_mapping?pretty | grep type | wc -l
890
它应该给我或多或少的映射中的字段数。字段很多，但不超过1000
为什么，如果我提交，比如说，develop分支，这不会出现在我的贡献中吗？
我预计，如果我将该分支合并到其中，master那么所有提交到develop 其他分支或其他分支的内容都将可见。但情况似乎并非如此。
无论如何要这样做吗？还是必须直接提交master？
与图书馆
import logging
当我使用方法.error(text)或 时.warning(text)，记录器将日志级别写入为 INFO、WARNING、ERROR 等。
我想知道是否有办法更改字符串WARNING，例如更改为WARN（并改为更改ERROR为ERR）。
太长了；我想按照我喜欢的方式更改消息的文本日志记录级别（“调试”、“信息”、“警告”、“错误”、“严重”）...有没有办法做到这一点？
我有一个JSON,可以通过时间和使用的情况下更改类可能是unconvenient,因为我需要每次改变它的结构的JSON变化.
例如,如果我有这样的JSON:
val json= """{
"accounts": [
{ "emailAccount": {
"accountName": "YMail",
"username": "USERNAME",
"password": "PASSWORD",
"url": "imap.yahoo.com",
"minutesBetweenChecks": 1,
"usersOfInterest": ["barney", "betty", "wilma"]
}},
{ "emailAccount": {
"accountName": "Gmail",
"username": "USER",
"password": "PASS",
"url": "imap.gmail.com",
"minutesBetweenChecks": 1,
"usersOfInterest": ["pebbles", "bam-bam"]
}}
]
}"""
我可以通过以下方式访问它:
val parsedJSON = parse(json)
parsedJSON.accounts(0).emailAccount.accountName
我想检测“复制到剪贴板”的事件，因此当用户选择字符串或网址后，点击copy to clipboard.
您知道如何在 Android 环境中进行检查吗？
如何从像这样的迭代器中获取
val it = Iterator("one","two","three","four","five")
像地图一样
Map(four -> 4, three -> 5, two -> 3, five -> 4, one -> 3)
var m = Map[String, Int]()
while (it.hasNext) {
val cell = it.next()
m += (cell -> cell.length())
}
这是一个使用的解决方案,var但我想只使用Immutable和val变量.
如果我使用该for yield语句,返回的对象将是一个Iterator[Map],我不希望这样:
val m = for(i<- it if it.hasNext) yield Map(i->i.length())
我安装了Cloudera Manager 5.13.
在第一次安装和运行时YARN ..我有以下错误

[....和其他行的堆栈异常错误]
所以基本上问题是HDFS文件夹的权限.
像:
sudo -u hdfs hdfs dfs -chmod -R 777 /
将修复错误.
但我的问题是......不是不安全吗？为什么Cloudera不处理此权限？
