**Hi,**
**I installed two-node ES 5.1.1 cluster, use Java client to create index, update its mapping and indexing sample data. From time to time, I got timeout exception for "create-index" action, if try it again, it could either work or not. Please advise what could be the issue with my cluster? Is there anyway to change the config for 30s timeout? Thanks!**

**I also use the remote reindex to migrate indexed data from ES 1.4.4 to 5.1.1. From time to time, got similar exceptions for the action "put-mapping". Any solution or suggestion to it? The index has 6M docs, each doc has a different doc type, but, all docs have the same field mappings (8 fields)**
