Hi ,

 

im unable to connect impala shell ( kerberised cluster ) with below: command  on Edge node 

impala-shell -i hostname.abc.com -d default -k

case scenario :  we have two Edge node A and B , able to connect on edgenode A  and unable to connect on edgenode  B with same credentials. checked with different user is it also same as working  on Edge node A and edgenode B . 

observed that both have different python version  A has 2.7.5 as default and B has 3.7.0 is this the cause of connection , if yes how to rectify. 

ERROR screenshot shared.

Hi Vidya , 

 

Issue has been resolved by setting path : 

export PATH=/opt/cloudera/parcels/CDH-5.15.1-1.cdh5.15.1.p0.4/bin:/usr/bin/python2:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/opt/anaconda3/bin:/opt/anaconda3/condabin

Hello Syed,

 

Yes, the impala is compatible with Python version 2.7.5.

You can try the below steps in edge node B

virtualenv venv -p python2

cd venv

source bin/activate

(venv) impala-shell

Yes, you need to switch to venv everytime or you need to reinstall python with the 2.7.5 version.

Hi,

Me sharing below line from bashrc of a particular user 

# .bashrc

export PYSPARK_DRIVER_PYTHON="jupyter"
export PYSPARK_DRIVER_PYTHON_OPTS="notebook"
export SPARK_HOME="/opt/cloudera/parcels/CDH-5.15.1-1.cdh5.15.1.p0.4/lib/spark/"
export PATH="$PATH:/opt/cloudera/parcels/CDH-5.15.1-1.cdh5.15.1.p0.4/bin/"

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi

# >>> conda initialize >>>

# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
eval "$__conda_setup"
else
if [ -f "/opt/anaconda3/etc/profile.d/conda.sh" ]; then
. "/opt/anaconda3/etc/profile.d/conda.sh"
else

export PATH="/opt/anaconda3/bin:$PATH"
export PATH="/opt/anaconda3/condabin:$PATH"
fi
fi
unset __conda_setup

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions
alias python=/usr/bin/python2
export PYSPARK_PYTHON=/usr/src/Python-3.7.0/python
