Hi  
I am using ES-0.90.0.RC2

I created an index "test" in ES , with 5 shards and 1 replica.  
I am trying to delete a mapping in ES .  
When i issue the delete command

[http://192.168.145.144:9200/test/content/\_mapping](http://192.168.145.144:9200/test/content/_mapping) through REST Client,  
with method as DELETE , it returns the status

{"ok":true}

After checking through the stats/status api, it reflects logically deleted  
documents, but no reduction in size .Size remains same on the physical disk  
as well.

So i tried optimizing the index, with command

[http://192.168.145.144:9200/test/\_optimize?only\_expunge\_deletes=true](http://192.168.145.144:9200/test/_optimize?only_expunge_deletes=true)  
through the REST Client, with method as get , and it returns status

{"ok":true,"\_shards":{"total":10,"successful":10,"failed":0}}

But, on the ES console , it shows Some exception for each primary shard.

Still , on checking the status/stats API , size is still the same (before  
deletion) and on physical disk as well.

Please help me out , as am not able to figure out exactly where am i going  
wrong.

Thanks in Advance

Hi  
Seems like it was some sort of a bug in 0.90.0RC2 , found a workaround ,  
after deletion call, a create mapping call , and then issue optimize .

otherwise , in 0.90.1 , it works fine.
