Log Context

Log”snapshot is not allowed”classname  is IndexShard.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

final IndexShardState state = this.state; // one time volatile read
  // we allow snapshot on closed index shard; since we want to do one after we close the shard and before we close the engine
  if (state == IndexShardState.STARTED || state == IndexShardState.CLOSED) {
  return getEngine().acquireLastIndexCommit(flushFirst);
  } else {
  throw new IllegalIndexShardStateException(shardId; state; "snapshot is not allowed");
  }
  }
