We're using Elasticsearch 1.2.2 in our cluster, and have 3 dedicated master
nodes. Last night, two of these master nodes (ES-SEARCH-64 and
ES-SEARCH-65) became primary master alternately in a period, and we found
quite a few 'marked shard as started, but shard has not been created, mark
shard as failed' in the logs, see an example below. Does anyone know what
this means? and why it happened?
