How to create a cache with 2 backups using REST

[Prachi Garg <pg...@gridgain.com>]

Hi Alexey,

I used the following command to create a cache with 2 backups -
http://localhost:8080/ignite?cmd=getorcreate&cacheName=myNewPartionedCache&backups=2

This is the response -
{“successStatus”:0,“error”:null,“response”:null,“sessionToken”:null}

Here, it does not give me much info in the response. Looking at the status,
which is 0, I can just assume that everything went ok.(I guess..)

Then I try to get the cache metadata, using this command -
http://localhost:8080/ignite?cmd=metadata&cacheName=myNewPartionedCache

I get this error - {“successStatus”:1,“error”:“Failed to handle request:
[req=CACHE_METADATA, err=Failed to request meta data. myNewPartionedCache
is not found]“,”response”:null,“sessionToken”:null}

What am I missing here?

-P

Prachi,

This is a bug in REST "metadata"command.

I created issue: REST: metadata command failed on cluster of size 1.
https://issues.apache.org/jira/browse/IGNITE-8777

If you start 2 nodes,  "metadata"command will be executed correctly.
