-----------------------------------
Sorry for inconvenience, i searched the bug list and did not find any related
so decided to create an issue here :(
Here are the details :
I have collections according to year for my data which are divided into shards
according to months. (e.g collection name col_2013, shards ->
201301,201302,...,201312 / col_2014 -> 201401, 201402, 201403 etc.)
For all collections i created an alias to dynamically manage my data. (e.g
col_arc -> colr_2013, col_2014, col_2015, col_2016)
When i query my data with adding "shards" parameter for routing requests to
specific shards (since i have lots of shards each contain huge amount of data)
solr raises the error mentioned above. If alias points to only 1 collection, it
behaves as it is expected. (no excepiton raised, the request is routed to given
shards)
http://localhost:8983/solr/col_arc/select?indent=on&q=*:*&wt=json&shards=201301,201302,201303
{
"responseHeader":{
"zkConnected":true,
"status":503,
"QTime":19,
"params":{
"q":"*:*",
"shards":"201301,201302,201303",
"indent":"on",
"wt":"json"}},
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","org.apache.solr.common.SolrException"],
"msg":"no servers hosting shard: ",
"code":503}}
> Distributed searches with the shards parameter does not work with collection
> alias
