I ran into a problem with UNASSIGNED shards in an Elasticsearch cluster after experiencing a degraded EC2 instance.
I did the usual steps to solve:
and ran into a heap of problems.
I installed curator_cli using
pip install elasticsearch-curator
but found that, despite reams of pages using the command
delete_indices, curator kept saying
No such command.
Someone else had experienced this:
The solution seemed to be to downgrade some library called Click.
So I downgraded Click with:
pip install click==6.7 elasticsearch-curator==5.5.4
Now I’m running into
elasticsearch.exceptions.ElasticsearchException: Unable to create client connection to Elasticsearch. Error: Elasticsearch version 1.7.5 incompatible with this version of Curator (5.5.4)
It seems there’s a compatibility issue.
