Running into an issue on elastic. Right now elastic is not returning anything, and this is the only thing that keeps being output to the log file: [2012-12-23 16:30:29,270][WARN][http.netty] [Lykos, Karl] Caught exception while handling client http traffic, closing connection [id: 0x4c97a006, /172.16.225.14:57157 =\> /172.16.225.22:9200] java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:185) at java.net.SocketInputStream.read(SocketInputStream.java:199) at java.io.FilterInputStream.read(FilterInputStream.java:83) at java.io.PushbackInputStream.read(PushbackInputStream.java:139) at org.elasticsearch.common.netty.channel.socket.oio.OioWorker.process(OioWorker.java:65) at org.elasticsearch.common.netty.channel.socket.oio.AbstractOioWorker.run(AbstractOioWorker.java:75) at org.elasticsearch.common.netty.channel.socket.oio.OioWorker.run(OioWorker.java:52) at org.elasticsearch.common.netty.util.ThreadRenamingRunnable.run(ThreadRenamingRunnable.java:102) at org.elasticsearch.common.netty.util.internal.DeadLockProofWorker$1.run(DeadLockProofWorker.java:42) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:636) Any ideas on what is happening here? -- ---

Update: I tried getting it out of an UNASSIGNED state with no luck When I try to do a simple count on an index, I get this: {"count":0,"\_shards":"total":1,"successful":0,"failed":1,"failures ":[{"index":"wm\_index","shard":0,"reason":"BroadcastShardOperationFailedExc eption[[wm\_index][0] No active shard(s)]"}]}} And this is what I get when I curl :9200/\_cluster/health: {"cluster\_name":"elasticsearch","status":"red","timed\_out":false,"number\_of\_nodes":1,"number\_of\_data\_nodes":1,"active\_primary\_shards":0,"active\_shards":0,"relocating\_shards":0,"initializing\_shards":0,"unassigned\_shards":1} curl -XPOST 'localhost:9200/\_cluster/reroute' -d '{ "commands" : [ {"allocate" : {"index" : "wm\_index", "shard" : 0, "node" : "XKYnqpKeSaG87fHixwyeVQ", "allow\_primary" : "true"}} ] }' -- ---

You have a cluster state of "red". There are many reasons. The exception you show tells us, a client aborted the connection, it is probably not related to the cause. Does a node restart help? Jörg -- ---

I'm also getting this exception, with v2.4.1. Any resolution to this? Here's my stack trace. Right now I don't have anything running except Elasticsearch. ``` [2016-10-05 22:22:03,995][WARN][http.netty] [Hulk] Caught exception while handling client http traffic, closing connection [id: 0xb398933b, /127.0.0.1:51466 :> /127.0.0.1:9200] java.lang.IllegalArgumentException: invalid version format: ﾏ~ ￉￁ﾋﾹ at org.jboss.netty.handler.codec.http.HttpVersion.(HttpVersion.java:94) at org.jboss.netty.handler.codec.http.HttpVersion.valueOf(HttpVersion.java:62) at org.jboss.netty.handler.codec.http.HttpRequestDecoder.createMessage(HttpRequestDecoder.java:75) at org.jboss.netty.handler.codec.http.HttpMessageDecoder.decode(HttpMessageDecoder.java:191) at org.jboss.netty.handler.codec.http.HttpMessageDecoder.decode(HttpMessageDecoder.java:102) at org.jboss.netty.handler.codec.replay.ReplayingDecoder.callDecode(ReplayingDecoder.java:500) at org.jboss.netty.handler.codec.replay.ReplayingDecoder.cleanup(ReplayingDecoder.java:554) at org.jboss.netty.handler.codec.frame.FrameDecoder.channelDisconnected(FrameDecoder.java:365) ``` ---
