I am trying to install conda on EMR and below is my bootstrap script, it looks like conda is getting installed but it is not getting added to environment variable. When I manually update the
$PATH variable on EMR master node, it can identify
conda. I want to use conda on Zeppelin.
I also tried adding condig into configuration like below while launching my EMR instance however I still get the below mentioned error....

Seems you need to upgrade
pip, see this question.
But there can be multiple
pips in a Dataproc cluster, you need to choose the right one.
For init actions, at cluster creation time,
/opt/conda/defaultis a symbolic link to either
/opt/conda/anaconda, depending on which Conda env you choose, the default is Miniconda3, but in your case it is Anaconda. So you can run either
/opt/conda/default/bin/pip install --upgrade pipor
/opt/conda/anaconda/bin/pip install --upgrade pip.
For custom images, at image creation time, you want to use the explicit full path,
/opt/conda/anaconda/bin/pip install --upgrade pipfor Anaconda, or
/opt/conda/miniconda3/bin/pip install --upgrade pipfor Miniconda3.
So, you can simply use
/opt/conda/anaconda/bin/pip install --upgrade pip for both init actions and custom images.

pip3 install pandas a shot.

You are deploying zeppelin-server on Kubernetes, right? Your yaml file with the service account looks good as I suppose, however to be sure that this works, you should follow the next steps:
kubectl get clusterrole
and you should get
- check if your account 'flink' has a binding to clusterrole "zeppelin-server-role"
kubectl get clusterrole clusterrolebinding
if there is no, you can create it by the following command:
kubectl create clusterrolebinding zeppelin-server-role-binding --clusterrole=zeppelin-server-role --serviceaccount=default:flink
- finally, check if you really act as this account:
kubectl get deploy flink-deploy -o yaml
if you can't see the settings "serviceAccount" and "serviceAccountName" from the output something like:
