Hi, I got a NPE when doing sth. like this: ``` BulkRequestBuilder brb = client.prepareBulk(); for (SolrTweet tw : tweets) { String id = Long.toString(tw.getTwitterId()); XContentBuilder source = createDoc(tw); ``` brb.add(Requests.indexRequest(indexName).type(getIndexType()).id(id).source(source)); } if (brb.numberOfActions() \> 0) brb.execute().actionGet(); I didn't properly check if the status was ok or not but no exception should be thrown ... Kind Regards, Peter. 2011-01-27 13:02:02,826 [elasticsearch[Eon][tp]-pool-1-thread-6] WARN org.elasticsearch.action.bulk - [Eon] Failed to update master on updated mapping for index [index2], type [tweet] java.lang.NullPointerException at org.elasticsearch.action.bulk.TransportShardBulkAction.updateMappingOnMaster(TransportShardBulkAction.java: 244) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrimary(TransportShardBulkAction.java: 168) at org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrimary(TransportShardBulkAction.java: 61) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java: 421) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction.access $200(TransportShardReplicationOperationAction.java:220) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction $1.run(TransportShardReplicationOperationAction.java:318) at java.util.concurrent.ThreadPoolExecutor $Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor $Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) ---

I will try and track this down and see why it happens...

Just want to add that I get basically the same error using a standard (non-bulk) HTTP PUT request. Elasticsearch returns a 200 indicating the index, type, and dynamic mapping have all been created. However, a subsequent search or GET for \_mapping fails. 200 Response: {"ok":true,"\_index":"myindex","\_type":"mytype1","\_id":"init"} Elasticsearch log: [WARN][action.index] [Grey King] Failed to update master on updated mapping for index [myindex], type [mytype1] java.lang.NullPointerException at org.elasticsearch.action.index.TransportIndexAction.updateMappingOnMaster(TransportIndexAction.java: 201) at org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java: 176) at org.elasticsearch.action.index.TransportIndexAction.shardOperationOnPrimary(TransportIndexAction.java: 66) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperationAction.java: 418) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction.access $200(TransportShardReplicationOperationAction.java:218) at org.elasticsearch.action.support.replication.TransportShardReplicationOperationAction $AsyncShardOperationAction $1.run(TransportShardReplicationOperationAction.java:316) at java.util.concurrent.ThreadPoolExecutor $Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor $Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680) On Jan 31, 2:16 pm, Karussell [tableyourt...@googlemail.com](mailto:tableyourt...@googlemail.com) wrote: > Thanks > > On 30 Jan., 22:19, Shay Banon [shay.ba...@elasticsearch.com](mailto:shay.ba...@elasticsearch.com) wrote: > > > I will try and track this down and see why it happens... > > > On Sunday, January 30, 2011 at 10:20 PM, Karussell wrote: > > > > > Hi, > > > > I got a NPE when doing sth. like this: > > > > BulkRequestBuilder brb = client.prepareBulk(); > > > for (SolrTweet tw : tweets) { > > > String id = Long.toString(tw.getTwitterId()); > > > XContentBuilder source = createDoc(tw); > > > > brb.add(Requests.indexRequest(indexName).type(getIndexType()).id(id).source (source)); > > > } > > > if (brb.numberOfActions() \> 0) brb.execute().actionGet(); > > > > I didn't properly check if the status was ok or not but no exception > > > should be thrown ... > > > > Kind Regards, > > > Peter. > > > > 2011-01-27 13:02:02,826 [elasticsearch[Eon][tp]-pool-1-thread-6] WARN > > > org.elasticsearch.action.bulk - [Eon] Failed to update master on > > > updated mapping for index [index2], type [tweet] > > > java.lang.NullPointerException > > > at > > > org.elasticsearch.action.bulk.TransportShardBulkAction.updateMappingOnMaste r(TransportShardBulkAction.java: > > > 244) > > > at > > > org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrim ary(TransportShardBulkAction.java: > > > 168) > > > at > > > org.elasticsearch.action.bulk.TransportShardBulkAction.shardOperationOnPrim ary(TransportShardBulkAction.java: > > > 61) > > > at > > > org.elasticsearch.action.support.replication.TransportShardReplicationOpera tionAction > > > $AsyncShardOperationAction.performOnPrimary(TransportShardReplicationOperat ionAction.java: > > > 421) > > > at > > > org.elasticsearch.action.support.replication.TransportShardReplicationOpera tionAction > > > $AsyncShardOperationAction.access > > > $200(TransportShardReplicationOperationAction.java:220) > > > at > > > org.elasticsearch.action.support.replication.TransportShardReplicationOpera tionAction > > > $AsyncShardOperationAction > > > $1.run(TransportShardReplicationOperationAction.java:318) > > > at java.util.concurrent.ThreadPoolExecutor > > > $Worker.runTask(ThreadPoolExecutor.java:886) > > > at java.util.concurrent.ThreadPoolExecutor > > > $Worker.run(ThreadPoolExecutor.java:908) > > > at java.lang.Thread.run(Thread.java:662) ---
