Allocation fails on newly added nodes

Elastic Stack Elasticsearch

Hello Guys,

Anyone know why the below error occurs when shard allocation happens. We added a few nodes to the existing cluster and this started happening as soon as we enabled the allocations.

[indices:data/write/bulk[s][r]]]; nested: ElasticsearchSecurityException[action [indices:data/write/bulk[s][r]] requires authentication]; ], allocation_status[no_attempt]], expected_shard_size[856524144]

We aren't all guys :slight_smile:

Can you please share more of the log? It'd be good to see what is in the master node's log at this time too.
