python cannot connect hiveserver2

Question

I have tried use the example on https://cwiki.apache.org/confluence/display/Hive/Setting+Up+HiveServer2 but gets the following errors:

/usr/lib/python2.7/dis         


        

Answer 1

Setting up following environment variable worked for me:

SASL_PATH=/usr/lib/x86_64-linux-gnu/sasl2 

This is for Ubuntu

Answer 2

The above answers don't work in my case, I've also tried others. Finally, I've solved my problem (no idea if it works for you).

Just execute

export LD_LIBRARY_PATH=/usr/lib64:/usr/local/lib:$LD_LIBRARY_PATH

before running your script.

My original LD_LIBRARY_PATH is /usr/local/lib:/usr/lib64

Answer 3

You are missing some dependencies, make sure you install cyrus-sasl-devel and cyrus-sasl-gssapi:

On an RHEL-based distro:

sudo yum install cyrus-sasl-devel cyrus-sasl-gssapi cyrus-sasl-md5 cyrus-sasl-plain

... or on a Debian-based distro:

sudo apt-get install sasl2-bin libsasl2-2 libsasl2-dev libsasl2-modules

Per @KenKennedy, also add the libsasl2-modules-gssapi-mit package if using GSSAPI for authentication.

1 In hive-site.xml, set configuration as below:

<property>
   <name>hive.server2.authentication</name>
   <value>NOSASL</value>
</property>

2 pyhs2 program codes changes as below:

with pyhs2.connect(host='localhost',
                   port=10000,
                   authMechanism="NOSASL",
                   user='user',
                   password='password',
                   database='default') as conn:

Please note that username and password cannot be empty, add any username and password when connects to pyhs2
