SearchParseException: Parse Failure [No mapping found for [@timestamp] in order to sort on]

I've installed elasticsearch-taste(1.6.0-SNAPSHOT) with elasticsearch(1.6.1) When I run first step it's failed to create index cat u.data | awk '{system("curl -XPOST localhost:9200/movielens/_taste/event?pretty -d "{"user":{"id":" $1 "},"item":{"id":" $2 "},"value":" $3 ","timestamp":" $4 "000}"")}'

Here is the exception Failed to execute [org.elasticsearch.action.search.SearchRequest@6e4a7280] org.elasticsearch.search.SearchParseException: [movielens][4]: query[system_id:196],from[-1],size[1]: Parse Failure [Failed to parse source [{"size":1,"query":{"term":{"system_id":196}},"fields":"user_id","sort":[{"@timestamp":{"order":"desc"}}]}]] at org.elasticsearch.search.SearchService.parseSource(SearchService.java:747) at org.elasticsearch.search.SearchService.createContext(SearchService.java:572) at org.elasticsearch.search.SearchService.createAndPutContext(SearchService.java:544) at org.elasticsearch.search.SearchService.executeQueryPhase(SearchService.java:306) at org.elasticsearch.search.action.SearchServiceTransportAction$5.call(SearchServiceTransportAction.java:231) at org.elasticsearch.search.action.SearchServiceTransportAction$5.call(SearchServiceTransportAction.java:228) at org.elasticsearch.search.action.SearchServiceTransportAction$23.run(SearchServiceTransportAction.java:559) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source)
