Hi,

I upgraded my elasticsearch setup from elasticsearch-1.4.1-1 to elasticsearch-1.7.0

Before upgrade, the system health was green. After upgrade, all the shards have gone to unassigned state.  
So I again uninstalled elasticsearch1.7 and installed elasticsearch 1.4.1-1 again.

Still the health state is not changing to green.  
There is no indication of problem in the logs.

Following is the health status of elasticsearch.  
{  
"cluster\_name" : "ms2\_stage\_elk",  
"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" : 269  
}

Please help.

Is there anything interesting in the ES log file?
