I am trying the sample impyla code from
And getting "impala.error.HiveServer2Error: Failed after retrying 3 times"
impyla is installed on the hadoop (CDH-5.3.2) node I log in to
from impala.dbapi import connect
conn = connect(host='my.impala.host', port=21050)
cursor = conn.cursor()
cursor.execute('SELECT * FROM youval_db.accounts_info LIMIT 10')
print cursor.description # prints the result set's schema
results = cursor.fetchall()
Where for "my.impala.host" I used the the impala host I got from the cloudera manager.
(tried with host from the following groups: Impala Catalog Server Default Group, Impala Daemon Default Group and Impala StateStore Default Group)
got the same error for All.
Also tried with
conn = connect()
It did not work as well.
Any suggestion on how to make it work?
Been getting the same error when I was trying to connect to the impala instance on a kerberized cluster! Any particular reason why we get this??
