A memo connected to HiveServer2 of EMR with python

Tried environment

hiveServe2 With AMI 3.3.1, it is started as soon as the cluster is ready.

$ ps -ef | grep hiveserver2
hadoop   27009   539  0 02:03 pts/9    00:00:00 grep hiveserver2
root     31866     1  0 Dec08 pts/1    00:00:00 su - hadoop -c bash -c /home/hadoop/hive/bin/hive --service hiveserver2

That's why it's running.

You can easily start and stop it because a script is prepared.

$ sudo /etc/init.d/hive-serverd start
$ sudo /etc/init.d/hive-serverd stop

The log is in *** / mnt / var / log / hive-serve ***, so check it for the time being.

Install and connect pyhs2

The HiveServer2 client for python has pyhs2, It's easy to install with pip, so I'll give it a try.

$ sudo pip install pyhs2

It's ok, so install this one before running it.

$ sudo yum install cyrus-sasl-devel.x86_64

You should be able to enter safely with this.

But this pip is / usr / bin / python2.7 It is used here / usr / bin / python Not here. This may have been added during Hue installation.

After that, borrow sample You can connect by rewriting user and password to ** hive **.
