I am running 3 node Elasticsearch-1.3 cluster. One of the primary shards for an index that has no more documents being indexed to it, keeps bouncing from node to node. No its not relocating. Allocating the shard to any one node doesn't work. What can I do to stabilize it? Thanks -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Bouncing? Does it allocate or just sit in a allocating state?

By bouncing I mean the shard sits on one node for a little less than a minute then moves over to a second node, then back to the first node after a few seconds. It stays in INITIALIZING state.

I have had such a problem with a few shards. The allocation fails with the following message: RecoveryFailedException: Recovery failed from X into Y; nested: RemoteTransportException Y; nested: RecoveryEngineException ... Phase[2] Execution failed; nested: RemoteTransportException ...[index/shard/recovery/translogOps]]; nested: MapperParsingException[failed to parse [...]]; nested: ElasticsearchIllegalArgumentException[unknown property [foo]]; ]] In this case it seems dynamic-mapping for property foo wasn't propagated to all shards, now a few shards that somehow don't know the mapping for foo are not able to initialize on any node. I need to find out why the mapping for field foo is unknown though. Doesn't log tell you why its not able to initialize the shard?
