Hi Lianet / Jeff, Thanks for the review.
LM5: The kafka-share-groups.sh also uses “—describe” to show offsets information. Change to use “—describe —state —verbose” to show group level information in kafka-share-groups.sh. LM6: Update the example. LM7: Add a description to mention “—verbose” is a new option in ShareGroupCommandOptions. JK2: Yes, add the statement about format change for ASSIGNMENT value.
