Issue with Stream nodes,All partitions are under replicated.
Hi All,
Currently my stream nodes are having issue in the partitions. All the partitions are under under replicated in one of the stream node and in another there are no leaders. I just want to clear the partitions and want to re distribute the load among the nodes. Are there any steps to perform this or any help on this will help me.
Thanks

The issue occurs when there's handshake between two stream nodes disturbed. Try to accommodate time to monitor and see if the Under-Replicated count is going down while monitoring the Console messages in Stream nodes.
If not, You can clean up the Kakfka data in both the stream nodes will solve the issue.
The above solution is precisely works for Pega Containerization environment but for On-Prem, You'll need to validate the Queue Procssesors are in running state or not which is tagged with Stream Node. If the Queue Processors are runnning fine, YOu can proceed to clear the Kafka data in stream nodes, One by one ONLY. Do not perofm the cleanup activity in both stream nodes in On-Prem Method parallely.
