TTransportException: TTransportException(type=4, message='TSocket read 0 bytes')

[mohamedniyaz1996]

I tried to connect to remote Datanode of HBase cluster of version 2.1.0-chd6.2.1 like below:

import happybase
connection = happybase.Connection("10.22.151.68")
print(connection.tables())

But I am getting below error message:

TTransportException: TTransportException(type=4, message='TSocket read 0 bytes')

But with Hbase version of 0.98.6-cdh5.3.0 it is printing tables properly. Please help me to figure out why it is not connecting to new version of HBase.

I tried using below block and it started working:

import happybase
connection = happybase.Connection("10.22.151.68",port=9090,transport="framed",protocol="compact")
print(connection.tables())

At newer version of HBase-2.1.0 , protocol had been modified to compact from binary which is set as default-value at happybase - Connection object
