Rerouting shards in cluster

[moni15moni (mohankumar)]

Hi

In 2.x Es we have used the following rerouting command to move the INITIALIZING shard to STARTED state.

curl -XPOST "http://172.19.0.16:9200/_cluster/reroute" -d'
{
"commands": [{
"allocate": {
"index": "fw-dd-2017-06-06",
"shard": 1,
"node": "172.19.0.16",
"allow_primary": 1
}
}]
}'

I heard ,In ES 5.x they have changed the option to Primary and replica based,
Can anyone share the sample syntax in 5.x

You shouldn't need to do this. What is making you want to run this command?

If in case any hard ware failure s on the particular node, then the shards are like orphan, It's keep on the staus of INTIALIZING for Long days.
