如何绕过快乐基地"TApplicationException: Internal error processing mutateRows"错误?



我正在使用happybase连接到我的HBase数据库。我做了一个名为"irisSample"的示例表。这是我遇到问题的代码部分-

import happybase
from happybase import *
import json
connection = happybase.Connection('<ip-address>', '9090')
table = connection.table('irisSample')
n = 0
x = 1
for u in y:
    data = {'petalWidth':points['petalWidth'][n], 'sepalLength':points['sepalLength'][n], 
          'petalLength':points['petalLength'][n], 'label': u}
    row = 'row' + str(x)
    table.put(row, {'flowers': str(data)})
    n += 1
    x += 1

我得到以下内容。

TApplicationException                     Traceback (most recent call last)

   1595     result = mutateRows_result()
   1596     result.read(self._iprot)
TApplicationException: Internal error processing mutateRows

我也尝试了json.dumps(data)而不是抛出相同异常的str(data)

从我收集的信息来看,这似乎更像是一个节俭问题,但我可能是错的。我可能不得不看看星际基地。我不知道,这就是为什么我要问你们。

看起来在您的"数据"对象中,您没有提供列系列以及列名称。

data = {'petalWidth':points['petalWidth'[n], 'sepalLength':points['sepalLength'][n], 'petalLength':points['petalLength'][n], 'label': u}

您需要在每个列值之前都有列系列。 例如,假设您的列系列是"cf",那么您想要的不是"petalWidth",而是"cf:petalWidth"。

data = {'cf:petalWidth':points['petalWidth'[n], 'cf:sepalLength':points['sepalLength'][n], 'cf:petalLength':points['petalLength'][n], 'cf:label': u}

这样做为我修复了 mutateRows 错误。

我在这里找到了答案。它需要一个 REST 框架在未使用的端口上运行。然后,我连接到该端口,并能够看到 Hbase 中所有表的列表并将数据插入数据库。该命令./hbase-daemon.sh start rest -p <unused port number> 。我在任何地方都找不到答案,甚至几天都没有人发表评论,所以我希望这对您有所帮助!这是代码。我最终使用了starbase.

import starbase
from starbase import Connection
c = Connection(host='<ip-address>', port=8000)

顺便说一下,8000 是默认端口。

t = c.table('irisSample')
for flower in range(len(labels)):
    data = {'petalWidth':X[flower][3], 'petalLength':X[flower][2], 
              'sepalLength':X[flower][0], 'sepalWidth':X[flower][1], 'cluster': labels[flower]}
    n += 1
    row = 'row' + str(n)
    t.insert(row, {'flowers': data})
