Description
Here is an example command an error in the 3.1.9 shell when it is configured to use find command:
mongos> db.messages.find({},{_id:0,'headers.From':1,'headers.Subject':1,'headers.Date':1}).batchSize(10);
|
assert: command failed: {
|
"ok" : 0,
|
"errmsg" : "Retried 10 times without establishing shard version on a reachable host.",
|
"code" : 63
|
} : undefined

And here is what you get with the 3.0.6 shell or the 3.1.9 shell with wire protocol find:
mongos> db.messages.find({},{_id:0,'headers.From':1,'headers.Subject':1,'headers.Date':1}).batchSize(10);
|
Error: error: {
|
"$err" : "Retried 10 times without establishing shard version on a reachable host.",
|
"code" : 63
|
}
