mutil_get not aviliable in opentsdb2.4.0

[lloverj]

in opentsdb2.4, I want to use mutil-get,but fond in TsdbQuery.java ,multiget_with_search can't set.
so mutil-get can't use.
/** Whether or not to use the search plugin for multi-get resolution. */
private boolean multiget_with_search;

if (use_multi_gets && override_multi_get && multiget_with_search) {
  row_key_literals_list = Lists.newArrayList();
}

      if (filters != null) {
        if (use_multi_gets && override_multi_get && multiget_with_search) {

}
MultiGetQuery.java
if (tags == null) {
throw new IllegalArgumentException("Tags list cannot be null or empty");
}

Tags list cannot be null or empty

[lloverj]

config is :
tsd.query.multi_get.enable = true
tsd.query.multi_get.batch_size = 1024
tsd.query.multi_get.concurrent = 20
tsd.query.multi_get.get_all_salts = true

Can you post what the query you are trying to run is ? It's hard work out what's going wrong without it.

What are you sending to /api/query that's getting that response back ?

[Betula-L]

curl http://10.69.33.36:4242/api/query -H "Content-Type:application/json" -X POST -d @-

{
    "start": 1568412279,
    "end": 1569412579,
    "queries": [
        {
            "aggregator": "none",
            "metric": "bs__performance__candidates__sum",
            "rate": "true",
            "tags": {
                "app": "*"
            }
        }
    ]
}

This query is as followed as http://opentsdb.net/docs/build/html/api_http/query/index.html

If multi_get disabled it works well, while it is broken if multi_get was on.

How are you using the search plugin?

[Betula-L]

Sorry. I got it. There must be set some search plugin.

[Betula-L]

However, Tags list cannot be null or empty error message is so confused. Actually, it is caused by no search plugin.
