hbase无法找到现有表

我设置了一个hbase集群来存储来自opentsdb的数据.最近由于重启了一些节点,hbase丢失了表"tsdb".我仍然可以在hbase的主节点页面上,但是当我点击它时,它给了我一个tableNotFoundException

我进入了hbase shell,尝试找到'tsdb'表,但得到了类似的消息

hbase(main):018:0> scan 'tsdb'

但是当我试图重新创建这个表时,hbase shell告诉我该表已经存在...

hbase(main):013:0> create 'tsdb', {NAME => 't', VERSIONS => 1, BLOOMFILTER=>'ROW'}

ERROR: Table already exists: tsdb!

我还可以在hbase shell中列出该表

hbase(main):001:0> list

看一下日志,我发现这应该是我的问题的原因

为什么OpenTSDB选择HBase进行时间序列数据存储？

如果有人对选择HBase作为OpenTSDB的数据存储引擎有所了解,我真的很感激吗？

还考虑了其他选择,例如Whisper(Graphite front-end + Carbon persistence)？

像HBase这样的面向列的数据库如何成为时间序列数据的更好选择？

使用HBase存储时间序列数据

我们正在尝试使用HBase来存储时间序列数据.我们目前的模型将时间序列存储为单元格中的版本.这意味着单元可能最终存储数百万个版本,并且此时间序列上的查询将使用HBase中 Get类上可用的setTimeRange方法检索一系列版本.

例如

{
    "row1" : {
        "columnFamily1" : {
            "column1" : {
                1 : "1",
                2 : "2"
            },
            "column2" : {
                1 : "1"
            }
        }
    }
}

这是在HBase中存储时间序列数据的合理模型吗？

将数据存储在多列中的备用模型(可以跨列查询)还是更合适的行？

如何在OpenTSDB和InfluxDB或其他TSDS之间做出选择？

它们都是开源的分布式时间序列数据库,用于度量的OpenTSDB,用于度量的InfluxDB和没有外部依赖性的事件,在另一个基于HBase的OpenTSDB上.

他们之间还有其他任何比较吗？

如果我想实时存储和查询指标,没有基于时间序列的恶化损失,那会更好吗？

HBase regionserver被中止,之后永远不会被提起

我在HBase上使用OpenTSDB(虚拟盒上的伪分布式Hadoop)以非常高的负载(~50,000记录/秒)发送数据.系统工作了一段时间,但突然下降了.我终止了OpenTSDB和HBase.不幸的是,我再也不能把它们搞砸了.每次我尝试运行HBase和OpenTSDB时,都会显示错误日志.在这里我列出了日志:

什么是OpenTSDB中的分块请求？

我正在使用Qt4将一些数据点发布到OpenTSDB服务器,该服务器不支持分块的HTTP请求.

代码基本上是这样的:

QNetworkRequest request(m_url);
request.setHeader(QNetworkRequest::ContentTypeHeader, QString("application/json"));
request.setHeader(QNetworkRequest::ContentLengthHeader, jsonRequest.toAscii().size());
m_networkAccessManager.post(request, jsonRequest.toAscii());

Run Code Online (Sandbox Code Playgroud)

jsonRequest是一个包含数据点的QString.这段代码不时被调用以将数据上传到服务器,它通常可以正常工作.但是,有时我从openTSDB收到错误,指出"不支持Chunked请求.".这似乎发生在请求变得更大时(并且更大,我的意思是一些KB的数据).

编辑:当问题出现时我已经完成了请求的tcpdump,事实上它并没有被看作是分块的:

选择TSDB进行一次性智能家居安装

我正在构建一个一次性的智能家居数据收集盒.它预计将运行在raspberry-pi级机器(~1G RAM)上,每天处理大约200K数据点(每个64位int).我们一直在使用vanilla MySQL,但性能开始崩溃,特别是对于给定时间间隔内的条目数量的查询.

据我了解,这基本上就是为时间序列数据库设计的.如果有的话,关于我的情况的不寻常的事情是音量相对较低,可用的RAM量也是如此.

快速浏览维基百科可以看出OpenTSDB,InfluxDB和BlueFlood.OpenTSDB建议使用4G的RAM,但这可能适用于高容量设置.InfluxDB实际上提到了传感器读数,但我找不到很多关于需要什么样的资源的信息.

好的,所以这是我的实际问题:是否有明显的红旗会使这些系统中的任何一个不适合我描述的项目？

我意识到这是一个火焰的邀请,所以我指望人们把它保持在明亮和乐于助人的一面.提前谢谢了!

发送Spark流量指标以打开tsdb

如何从我的spark流工作发送指标以打开tsdb数据库？我试图在Grafana中使用open tsdb作为数据源.你可以帮我一些我可以开始的参考资料.

我确实看到开放的tsdb记者在这里做类似的工作.如何整合Spark流媒体作业的指标来使用它？有没有简单的选择呢.

访问速度非常快的大数据

我面临一个问题:过程工厂的数据库.采样率为50 ms时,最多有50,000个传感器.所有测量值都需要存储至少3年,并且必须支持实时查询(即用户可以查看延迟小于1秒的历史数据).我最近阅读了一篇关于时间序列数据库的文章,现有很多选项:OpenTSDB,KairosDB,InfluxDB,......

我很困惑哪一个适合这个目的？任何人都知道这个请帮助我!

更新15.06.25

今天我运行一个基于OpenTSDB的测试.我使用Virtual Box创建了一个由3个CentOS x64 VM组成的集群(1个主服务器,2个从服务器).主机配置为8 GB RAM,核心i5.主VM配置为3 GB RAM,从站配置为1.5 GB RAM.我编写了一个python程序来向OpenTSDB发送数据,如下所示:

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("192.168.10.55", 4242))

start_time = time.time()
start_epoch = 1434192418;

for x in range(0, 1000000):
    curr_epoch = start_epoch + x

    tag1 = "put TAG_1 %d 12.9 stt=good\n" % (curr_epoch)
    tag2 = "put TAG_2 %d 12.9 stt=good\n" % (curr_epoch)
    tag3 = "put TAG_3 %d 12.9 stt=good\n" % (curr_epoch)
    tag4 = "put TAG_4 %d 12.9 stt=good\n" % (curr_epoch)
    tag5 = "put TAG_5 %d 12.9 …
