Install

To install the current release:

$ pip install rslib

Demo

dataframe2hive功能demo

功能描述: 通过洛阁组通过的hdfs上传接口实现本地dataframe上传至hive表('\t'分割)的功能。由于hive数据导入时不进行类型检查(不支持schema on write),我们不提供直接插入现有表分区的操作,而是建一张新表。用户需要管理好dataframe的列名。 由于洛阁接口的问题,上传文件会有报错信息,本接口有报错重连机制,一般是能上传成功的。大文件不建议上传,不过测试下来也比较稳定,1.3G文件能在10分钟内上传完成。

环境要求(在user_profile/basic镜像基础上)

$ apt-get update && apt-get install -y krb5-user krb5-config libkrb5-dev
$ pip install requests-kerberos==0.12.0 hdfs==2.5.8 kerberos==1.3.0
$ pip install rslib==1.3.1
$ pip install requirements.txt  #custom path
$ kinit -kt code/data/up_recommend.keytab up_recommend  #custom path

示例python代码

import pandas as pd
from rslib.utils import dataupload
df = pd.DataFrame({'bb': [1, 2, 3], 'c': [2, 2, 3], 'aa': ['4', '5', '6']})
table = 'up_nsh_tmp.diting_rslib_test_20191021'
dataupload.pandas2hive(df, table)  #no partition
dataupload.pandas2hive(df, table, partition='2019-10-21')  #add partition
