如何解决 happybase "TApplicationException: Internal error processing mutateRows" 错误？

Question

我正在使用 happybase 连接到我的 Hbase 数据库。我制作了一个名为 'irisSample' 的示例 table。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

我得到以下信息。

TApplicationException                     Traceback (most recent call last)

TApplicationException: Internal error processing mutateRows

我也试过 json.dumps(data) 而不是 str(data) ，后者引发了同样的异常。

从我收集的信息来看，这似乎更像是一个 Thrift 问题，但我可能是错的。我可能不得不看看 starbase。我不知道，这就是我问你们的原因。

Answer 1

我找到了答案here。它要求 REST 框架在未使用的端口上运行。然后我连接到那个端口，能够看到 Hbase 中所有表的列表并将数据插入数据库。命令是./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，所以我希望这对你有帮助！这是代码。我最终使用了 starbase.

import starbase
from starbase import Connection

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

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})

Answer 2

在您的 "data" 对象中，您似乎没有提供列族和列名。

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有列族。例如，假设您的列族是 "cf"，那么您想要 'cf:petalWidth'.

而不是 'petalWidth'

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

这样做修复了我的 mutateRows 错误。
