thrift.transport.TTransport.TTransportException: TSocket read 0 bytes报错解决-蒲公英云

thrift.transport.TTransport.TTransportException: TSocket read 0 bytes报错解决

一、问题描述

htrift版本：2.0.0-cdh6.0.1
hbase版本：1.2.0-cdh5.7.0

使用 thrift client with python 连接 hbase 报错：

File "C:\Users\HP\env1\lib\site-packages\thrift\transport\TSocket.py", line 132, in read
    message='TSocket read 0 bytes')
thrift.transport.TTransport.TTransportException: TSocket read 0 bytes

二、查找原因
1）hbase连接代码

from thrift.transport import TSocket
from thrift.protocol import TBinaryProtocol
from thrift.transport import TTransport
transport = TTransport.TBufferedTransport(TSocket.TSocket(10.201.7.113, int(port)))
protocol = TBinaryProtocol.TBinaryProtocolAccelerated(self.transport)

2） hbase-site.xml 配置如下

<property>
      <name>hbase.regionserver.thrift.framed</name>
      <value>true</value>
   </property>
   <property>
      <name>hbase.regionserver.thrift.compact</name>
      <value>true</value>
   </property>

3） thrift server日志如下：（/var/log/hbase/hbase-hbase-thrift-.log）

INFO  [main] mortbay.log: Started HttpServer$SelectChannelConnectorWithSafeStartup@0.0.0.0:9095
 DEBUG [main] thrift.ThriftServerRunner: Using compact protocol
 DEBUG [main] thrift.ThriftServerRunner: Using framed transport
 INFO  [main] thrift.ThriftServerRunner: starting TBoundedThreadPoolServer on /0.0.0.0:9090; min worker threads=16, max worker threads=1000, max queued requests=1000

由以上可知，是因为thrift 的server端和client端的协议不匹配造成的。

解决方案：
方案一：修改hbase-site.xml，禁用TFramedTransport和TCompactProtocol功能，即：

<property>
      <name>hbase.regionserver.thrift.framed</name>
     <value>false</value>
   </property>
   <property>
      <name>hbase.regionserver.thrift.compact</name>
      <value>false</value>
   </property>

重启thrift 服务器： service hbase-thrift restart

方案二：修改客户端代码

transport = TFramedTransport(TSocket('192.168.0.10', 9090))  
protocol = TCompactProtocol.TCompactProtocol(transport)  
client = Hbase.Client(protocol)  
transport.open()
