PPML document needs to be refined and corrected

[jenniew]

PPML user guide is not clear and lack of some essential information. And also there are errors for the scripts. For example, For 2.1 it runs ./ppml/scripts/generate-keys.sh, it will run keytool. But no information mentioned about how to install and run keytool command. And when run ./ppml/scripts/generate-keys.sh, it asks for input several passwords, but not sure what are these password for, which passwords should be match. And when run ./ppml/scripts/generate-keys.sh, it get error: base64: ./keys/keystore.jks: No such file or directory base64: ./keys/keystore.pkcs12: No such file or directory base64: ./keys/server.pem: No such file or directory base64: ./keys/server.crt: No such file or directory base64: ./keys/server.csr: No such file or directory base64: ./keys/server.key: No such file or directory.

2.3.1. Run ./build-docker-image.sh, if no proxy setting needed, the script would be fail. Should describe how to run if no proxy needed.

2.3.2.1. cp -r ../keys . this command cannot be executed as the directory is not correct. should be cp -r ../../../../keys .

To start the container, first modify the paths in deploy-local-spark-sgx.sh. No information about what should be set for the environment: export ENCLAVE_KEY_PATH=YOUR_LOCAL_ENCLAVE_KEY_PATH export DATA_PATH=YOUR_LOCAL_DATA_PATH export KEYS_PATH=YOUR_LOCAL_KEYS_PATH export LOCAL_IP=YOUR_LOCAL_IP

When run ./deploy-local-spark-sgx.sh would be failed. Get error: Unable to find image '10.239.45.10/arda/intelanalytics/analytics-zoo-ppml-trusted-big-data-ml-python-graphene:0.11-SNAPSHOT' locally

Haven't finish all steps. but so many unclear things and errors. Hard to follow. Please check all the steps and fix.

[glorysdj]

@ManfeiBai please help to fix the issues.

[ManfeiBai]

ok, I would fix it now

[ManfeiBai]

This following error has been fixed in the new PR(https://github.com/intel-analytics/analytics-zoo/pull/4617), and the path has been updated, the other errors are processing "And when run ./ppml/scripts/generate-keys.sh, it get error: base64: ./keys/keystore.jks: No such file or directory base64: ./keys/keystore.pkcs12: No such file or directory base64: ./keys/server.pem: No such file or directory base64: ./keys/server.crt: No such file or directory base64: ./keys/server.csr: No such file or directory base64: ./keys/server.key: No such file or directory."

I fixed the previous path issue manually, and tried the this script then got this error. The first test "basic_df_example" passed, the second test "schema_inference_example" failed with this error. Yes, java -version test passed.

When run ./deploy-distributed-standalone-spark.sh, it uses root user. But actually on Azure VM, no root user can be used. Can we provide a deploy script which uses non-root sudo user?

[ManfeiBai]

deploy-distributed-standalone-spark.sh

Could we use "sudo deploy-distributed-standalone-spark.sh" to run the script on Azure VM, rather than use "./deploy-distributed-standalone-spark.sh"?

[jenniew]

distributed-check-status.sh also need to support non-root user

[jenniew]

When run work load on cluster, we need to replace --master 'local[4]' with such lines:

--master 'spark://your_master_url' \
--conf spark.authenticate=true \
--conf spark.authenticate.secret=your_secret_key \

What should your_secret_key to be set to?

[ManfeiBai]

Thanks, solving it now
