AWS ElasticSearchService index_create_block_exception

Question

I'm trying to create a new index in AWS ElasticSearch cluster after increasing the cluster size and seeing index_create_block_exception. How can i rectify this? I tried searching but did not get exact answers. Thank you.

curl -XPUT 'http://<aws_es_endpoint>/optimus/'

{"error":{"root_cause":[{"type":"index_create_block_exception","reason":"blocked by: [FORBIDDEN/10/cluster create-index blocked (api)];"}],"type":"index_create_block_exception","reason":"blocked by: [FORBIDDEN/10/cluster create-index blocked (api)];"},"status":403}

Answer 1

According to AWS, the above exception is being thrown due to a low memory in disks.

For t2 instances, when the JVMMemoryPressure metric exceeds 92%, Amazon ES triggers a protection mechanism by blocking all write operations to prevent the cluster from getting into red status. When the protection is on, write operations will fail with a ClusterBlockException error, new indexes cannot be created, and the IndexCreateBlockException error will be thrown.

I'm afraid the issue is still on.
