We encounter a lot of log warning entries from the MetricsHistoryHandler saying

o.a.s.h.a.MetricsHistoryHandler Unknown format of leader id, skipping:
244550997187166214-server1-b.myhost:8983_solr-n_0000000094


I don't even know what this _MetricsHistoryHandler_ does, but at least there's a warning.


Looking at the code you can see that it has to fail if the hostname of the node contains a hyphen:

{code}
String[] ids = oid.split("-");
if (ids.length != 3) { // unknown format
  log.warn("Unknown format of leader id, skipping: " + oid);
  return null;
}
{code}
