Hi, I tried to index the following json under the search index and test1 type: {"test1" : "test1", "test2" : "test2"} But I get the following exception: org.elasticsearch.action.support.replication.ReplicationShardOperationFailedException: [search][4] at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java:337) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.access$400(TransportShardReplicationOperationAction.java:198) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction$1.run(TransportShardReplicationOperationAction.java:252) [elasticsearch-0.8.0.jar:na] at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) [na:1.6.0\_20] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) [na:1.6.0\_20] at java.lang.Thread.run(Thread.java:637) [na:1.6.0\_20] Caused by: org.elasticsearch.index.mapper.MapperException: Malformed content, a field with the same name as the type much be an object with the properties/fields within it at org.elasticsearch.index.mapper.xcontent.XContentDocumentMapper.parse(XContentDocumentMapper.java:306) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.index.mapper.xcontent.XContentDocumentMapper.parse(XContentDocumentMapper.java:272) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.index.shard.service.InternalIndexShard.innerIndex(InternalIndexShard.java:236) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.index.shard.service.InternalIndexShard.index(InternalIndexShard.java:228) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java:125) [elasticsearch-0.8.0.jar:na] node.data = true at org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java:56) [elasticsearch-0.8.0.jar:na] at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java:328) [elasticsearch-0.8.0.jar:na] ... 5 common frames omitted If I change the type name, or the json content, everything works fine.

Its not a bug, its a limitation in how elasticsearch works currently. I plan to remove it in the future if possible. -shay.banon On Sat, Jul 24, 2010 at 3:23 PM, Sergio Bossa [sergio.bossa@gmail.com](mailto:sergio.bossa@gmail.com)wrote: > Hi, > > I tried to index the following json under the search index and test1 type: > > {"test1" : "test1", "test2" : "test2"} > > But I get the following exception: > > org.elasticsearch.action.support.replication.ReplicationShardOperationFailedException: > [search][4] > at > org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java:337) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.access$400(TransportShardReplicationOperationAction.java:198) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction$1.run(TransportShardReplicationOperationAction.java:252) > [elasticsearch-0.8.0.jar:na] > at > java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) > [na:1.6.0\_20] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) > [na:1.6.0\_20] > at java.lang.Thread.run(Thread.java:637) [na:1.6.0\_20] > Caused by: org.elasticsearch.index.mapper.MapperException: Malformed > content, a field with the same name as the type much be an object with > the properties/fields within it > at > org.elasticsearch.index.mapper.xcontent.XContentDocumentMapper.parse(XContentDocumentMapper.java:306) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.index.mapper.xcontent.XContentDocumentMapper.parse(XContentDocumentMapper.java:272) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.index.shard.service.InternalIndexShard.innerIndex(InternalIndexShard.java:236) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.index.shard.service.InternalIndexShard.index(InternalIndexShard.java:228) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java:125) > [elasticsearch-0.8.0.jar:na] > node.data = true > at > org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java:56) > [elasticsearch-0.8.0.jar:na] > at > org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction$AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java:328) > [elasticsearch-0.8.0.jar:na] > ... 5 common frames omitted > > If I change the type name, or the json content, everything works fine. > > Am I missing something or is this an actual bug? > Thanks! > > Sergio B. > > -- > Sergio Bossa > [http://www.linkedin.com/in/sergiob](http://www.linkedin.com/in/sergiob) ---
