PyHive ignoring Hive config


PyHive ignoring Hive config

it helps some times PyHive is a thin client that connects to HiveServer2, just like a Java or C client (via JDBC or ODBC). It does not use any Hadoop configuration files on your local machine. The HS2 session starts with whatever properties are set server-side.
Same goes for ImPyla BTW.

Hope that helps Could not make it work using pyhive. Had to use paramiko insted below is the sample code
code :
import os
import paramiko
import time 

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts")))
ssh.connect('1.1.1.1', username='uid', password='pwd')
sshin, sshout, ssherr= ssh.exec_command('hive -e "create table test(key varchar(10),keyval varchar(200))"')

it fixes the issue The solution was to add the username in the connection line; conn = hive.Connection(host="HOST", username="USER")
From what I understand hive queries divided on many type of operations (jobs). While you are performing a simple query (ie. SELECT * FROM table) This reads data from the hive metastore no mapReduce job or tmp tables needed to perform the query. But as soon as you switch to more complicated queries (ie. using JOINs) you end up having the same error.
code :
# Import hive module and connect
from pyhive import hive
conn = hive.Connection(host="HOST", username="USER")
cur = conn.cursor()
query = "INSERT INTO table2 SELECT Col1, Col2 FROM table1"
cur.execute(query)

hop of those help? Using python in version 2.7 fixed this. I think there is issue with compatibility.

seems to work fine You can try using spark.hadoop.* prefix as suggested in Custom Spark Configuration section for version 2.3. Might work as well in 2.2 if it was just a doc bug :)
code :
spark-shell \
  --conf "spark.hadoop.hive.exec.dynamic.partition=true" \
  --conf "spark.hadoop.hive.exec.dynamic.partition.mode=nonstrict" \
  ...
