Description
I have got my trials localstack pro license and I could start localstack without any issue.
When I was trying the happy path of running emr steps within an EMR cluster under localstack I saw that all of them failed right away. (No log got generated for the EMR steps). So I looked back to the logs of localstack container and found this line during the creation of an EMR cluster:
Unable to start up EMR cluster: [Errno 13] Permission denied: '/var/lib/localstack/lib/hive/2.3.9/bin/schematool'
This is the simple script I ran to create the EMR cluster:
awslocal emr create-cluster \
--name "test-emr" \
--log-uri "s3://test-local/logs" \
--release-label "emr-6.11.0" \
--instance-groups '[{"InstanceCount":2,"InstanceGroupType":"CORE","Name":"keith-core","InstanceType":"c4.large","EbsConfiguration":{"EbsBlockDeviceConfigs":[{"VolumeSpecification":{"VolumeType":"gp2","SizeInGB":50},"VolumesPerInstance":1}],"EbsOptimized":true}},{"InstanceCount":1,"InstanceGroupType":"MASTER","Name":"test-master","InstanceType":"c4.large","EbsConfiguration":{"EbsBlockDeviceConfigs":[{"VolumeSpecification":{"VolumeType":"gp2","SizeInGB":32},"VolumesPerInstance":2}]}}]' \
--applications Name=Spark \
--scale-down-behavior "TERMINATE_AT_TASK_COMPLETION" \
--ebs-root-volume-size "50" \
--auto-termination-policy '{"IdleTimeout":10800}' \
--region "us-east-2"
Can anyone suggest what could possibly go wrong? Thanks

Research direction
Start by reproducing the issue with the provided awslocal emr create-cluster command and inspect the LocalStack container log for the schematool permission error. Trace the EMR cluster startup path involving /var/lib/localstack/lib/hive/2.3.9/bin/schematool. Done means the cluster starts successfully and its EMR steps generate logs.
