HBase Thrift with Python (Kerberos)

说在文前

本文内容是基于 Centos 7、HDP 3.0.0、HBase 2.0.0、Python 2.7 环境下，其他环境的童鞋选择性进行参考

安装 Thrift

安装依赖包

yum install -y automake libtool flex bison pkgconfig gcc-c++ libevent-devel zlib-devel python-devel ruby-devel openssl-devel

安装 boost (CentOS 7 必做)

wget https://dl.bintray.com/boostorg/release/1.64.0/source/boost_1_64_0.tar.gz
tar zxvf boost_1_64_0.tar.gz
cd boost_1_64_0
./bootstrap.sh
./b2 install

下载 Thrift

wget https://archive.apache.org/dist/thrift/0.10.0/thrift-0.10.0.tar.gz
tar zxvf thrift-0.10.0.tar.gz
cd thrift-0.10.0/
./configure  或者 ./configure --with-boost=/usr/local  --without-java --without-php
make
make install
# 进行确认安装成功
thrift -help

0.10.0 版本之前的不支持 python 3.5

生成 hbase.thrift

HDP 下 HBase 相应的安装目录下本身就已经存在 hbase.thrift 文件了，所以我们不需要自行创建了。

生成指定语言的代码

# hdp hbase.thrift 文件路径
cd /usr/hdp/3.0.0.0-1634/hbase/include/thrift/
# 生成 python
# 该路径下存在 thrift1 和 thrift2 两种，可以自行选择
thrift -gen py hbase1.thrift 或 thrift -gen py hbase2.thrift

启动 Thrift 服务

cd /usr/hdp/3.0.0.0-1634/hbase/bin/
./hbase-daemon.sh start thrift -p 9090 --infoport 8086

日志路径为 /var/log/hbase/

使用 Thrift 2 模式

./hbase-daemon.sh start thrift2 -p 9090 --infoport 8086
./hbase-daemon.sh stop thrift

Python 方式连接

Thrift_1 模式

from thrift.transport.TSocket import TSocket
from thrift.transport.TTransport import TBufferedTransport
from thrift.protocol import TBinaryProtocol
from hbase import Hbase

if __name__ == '__main__':
    transport = TBufferedTransport(TSocket('10.200.168.18', 9090))
    transport.open()
    protocol = TBinaryProtocol.TBinaryProtocol(transport)
    client = Hbase.Client(protocol)
    client.get()
    print(client.getTableNames())

Thrift_2 模式

from thrift.transport.TSocket import TSocket
from thrift.transport.TTransport import TBufferedTransport
from thrift.protocol import TBinaryProtocol
from hbase import THBaseService
from hbase.ttypes import TGet
import logging
if __name__ == '__main__':
    logging.basicConfig(level=logging.DEBUG)
    transport = TBufferedTransport(TSocket('10.200.168.18', 9090))
    transport.open()
    protocol = TBinaryProtocol.TBinaryProtocol(transport)
    client = THBaseService.Client(protocol)
    tget = TGet(row = '321ahah')
    tresult = client.get('shop', tget)
    for col in tresult.columnValues:
        print(col.qualifier, '=', col.value)
    print(client.send_get())
    transport.close()

Kerberos On Thrift

服务配置

core-site.xml

hadoop.proxyuser.hbase.groups=*
hadoop.proxyuser.hbase.hosts=*

hbase-site.xml

hbase.thrift.security.qop=auth
hbase.thrift.support.proxyuser=true
hbase.regionserver.thrift.http=false  # 使用http方式设为 true，binary 方式设为 false
hbase.thrift.keytab.file=/etc/security/keytabs/hbase.service.keytab 
hbase.thrift.kerberos.principal=hbase/[email protected] 
hbase.security.authentication.spnego.kerberos.keytab=/etc/security/keytabs/spnego.service.keytab 
hbase.security.authentication.spnego.kerberos.principal=HTTP/[email protected] 

重启 HDFS 和 HBase

重启 Thrift 服务

# 停止
./hbase-daemon.sh stop thrift
# 启动
kinit -kt /etc/security/keytabs/hbase.headless.keytab hbase-dev_dmp & /usr/hdp/3.0.0.0-1634/hbase/bin/hbase-daemon.sh start thrift -p 9090 --infoport 8086
# To test the thrift server in http mode the syntax is:
hbase org.apache.hadoop.hbase.thrift.HttpDoAsClient DEVDIP.ORG 9090 hbase true
# to test in binary mode the syntax is:
hbase org.apache.hadoop.hbase.thrift.DemoClient DEVDIP.ORG 9090 true

示例

/var/log/hbase

Python 方式连接

Thrift_1 模式

#!/usr/bin/env python
from thrift.transport import TSocket
from thrift.protocol import TBinaryProtocol
from thrift.transport import TTransport
from hbase import Hbase

# Apache HBase Thrift server coordinates (network location)
thriftServer = "dev-dmp5.fengdai.org"
thriftPort = 9090
# The service name is the "primary" component of the Kerberos principal the
# Thrift server uses.
# See: http://web.mit.edu/kerberos/krb5-1.5/krb5-1.5.4/doc/krb5-user/What-is-a-Kerberos-Principal_003f.html
# e.g. For a server principal of 'hbase/[email protected]', the primary is "hbase"
saslServiceName = "hbase"

# HBase table and data information
tableName = 'demo_table'
row = 'test2'
colName = "cf:name"

if __name__ == '__main__':
    # Open a socket to the server
    sock = TSocket.TSocket(thriftServer, thriftPort)
    # Set up a SASL transport.
    transport = TTransport.TSaslClientTransport(sock, thriftServer, saslServiceName)
    transport.open()
    # Use the Binary protocol (must match your Thrift server's expected protocol)
    protocol = TBinaryProtocol.TBinaryProtocol(transport)

    client = Hbase.Client(protocol)
    # Pass the above to the generated HBase clietn

    # Fetch a row from HBase
    print "Row=>%s" % (client.getRow(tableName, row, {}))

    # Cleanup
    transport.close()

Thrift_2 模式

#!/usr/bin/env python
from thrift.protocol import TBinaryProtocol
from thrift.transport import TSocket

from hbase import THBaseService
from hbase.ttypes import *

# Apache HBase Thrift server coordinates (network location)
thriftServer = "dev-dmp5.fengdai.org"
thriftPort = 9090
# The service name is the "primary" component of the Kerberos principal the
# Thrift server uses.

saslServiceName = 'hbase'

# HBase table and data information
tableName = 'DMP:demo'

coulumnValue1 = TColumnValue('cf', 'name')
coulumnValues = [coulumnValue1]
if __name__ == '__main__':
    socket = TSocket.TSocket(thriftServer, thriftPort)
    transport = TTransport.TSaslClientTransport(socket,host=thriftServer,service=saslServiceName,mechanism='GSSAPI')
    protocol = TBinaryProtocol.TBinaryProtocol(transport)
    client = THBaseService.Client(protocol)
    transport.open()

    result = client.get(tableName,get)
    print  result

问题

1、找不到libboost_unit_test_framework.a

使用源码本地编译 boos t安装；由于默认认为是 32 位，在 /usr/lib64/libboost_unit_test_framework.a 下是找不到的。可以通过 find libboost_unit_test_framework.a 定位文件真实路径，进行创建软连接。

find / -name libboost_unit_test_framework.a
ln -s /usr/local/lib/libboost_unit_test_framework.a /usr/lib64/libboost_unit_test_framework.a

2、kerberos.GSSError: ((' Miscellaneous failure (see text)', 851968), ('Error from KDC: UNKNOWN_SERVER', -1765328377))

# 日志信息
2019-05-08 20:36:10,529 WARN  [qtp176041373-47] http.HttpParser: Illegal character 0x1 in state=START for buffer HeapByteBuffer@28800d32[p=1,l=11,c=8192,r=10]={\x01<<<\x00\x00\x00\x06GSSAPI>>>\x02\x00\x00\x03P`\x82\x03L\x06\t*\x86H\x86\xF7\x12...\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00}

thriftServer = "10.200.168.7"
改为
thriftServer = "dev-dmp5.fengdai.org"
应该跟hbase/[email protected] => hbase/[email protected]

3、thrift.transport.TTransport.TTransportException: TSocket read 0 bytes

访问其实已经是通了，一直以为是客户端的问题，由于代码是通过 binary 方式访问，hbase.regionserver.thrift.http=false 应该设置为 false。
