Thanks for the gists, one way to simulate it faster is if you have a simpel
"main" program that uses the APIs to shows it. Can you do it?

Hey !
Thanks for following up !
Here's a full test that you can run.
>
You will jsut need a small lorem ipsum lib to generate the random
content and its available here :
[http://loremipsum.sourceforge.net/](http://loremipsum.sourceforge.net/)
As you will see content is wiped out of the index ... -\_-
Let me know what you think.
Regards,
Alexandre

Hey,
I took your code and ran it (on 0.17.9, and master), and it works for me.
Started both a 1 node cluster, and a 2 nodes cluster, and getting the
correct doc count on both cases. Any more data on your usage?
Btw, few notes on elasticsearch usage. You don't have to close an index to
put the mappings. Also, you can provide the mappings on index creation time
(so you remove the need to have the put mapping call). Last, if you want to
make things searchable "right away", you can simply call the refresh API.

Hi,
I just upgraded to 0.17.9 and re-ran the test I gave you... and the
problem was still here for me ...
Then I also modified my program a bit to take some of your comments
into account such as using refresh instead of sleep and NOT taking the
index down before putMapping.
And swoosh!! problem seems to have disappeared ...
I don't know what the source of the problem was but maybe there is a
hidden bug to investigate ...
Anyway thank you very much for your help.
I'll probably be bugging you again soon ...
Have a nice day !

Heya, it still should not happen. Can you give more details on your
deployment? How big is the cluster (how many nodes), configuration of it.

This is a dev / test server so I only have 1 node + 1 shard + 0
replicas
- 1 client connecting to it on the same machine.

Configuration is the default config I think ... I didnt change
anything as far as I can remember.

tried to recreate it again with a single node, 1 shard 0 replica index, and
still seems to work.. . Maybe you can check what config you used?

Ok so first of all here are all the configuration infos I can find in
my GUI :

Next I noticed something strange in my console that occurs when
triggering the createIndex(true) method of the test I gave you.
I don0t if its related to the same problem ...
In the logs I get the following :
Exception caught on netty layer [[id: 0x552297d7, /192.168.0.52:55124
=\> /192.168.0.52:9301]]
here is the full log of what happened just when creating the index.

Plus I am now sure that the index wiping problem ONLY occurs when the
index is taken down before putMapping calls in the test ...
If I comment out the close + open instructions the problem does not
occur ...
//
getClient().admin().indices().prepareClose(globalIndexname).execute().actionGet();
//
getClient().admin().indices().prepareOpen(globalIndexname).execute().actionGet();

Hey !
Just to let you know :
I just tested this again today on a different machine (32bit vista)
with a fresh install of ES 0.17.9 with no configuration changes from
what was downloaded and the weird index wiping still occurred.
When the index is taken down before putMapping (even though its not
necessary), the first putMapping call works fine and documents are
indexed but the seccond putMapping call (with same mapping) wipes
the index.
When the index is NOT taken down both putMapping call work fine and
the documents are still there after both calls.
Hope this helps you.
Cheers !
Alex
