已过时。

make a call to solrnode/admin/cores with the given params and give a callback. This is designed to be asynchronous because the system would want to batch the calls made to any given node

参数:

node - The node for which this call is made

params - The params to be passed to the Snitch counterpart

klas - The name of the class to be invoked in the remote node

callback - The callback to be called when the response is obtained from remote node. If this is passed as null the entire response map will be added as tags

remoteCallback

public void remoteCallback(SnitchContext ctx,
                           Map<String,Object> returnedVal)

指定者:

remoteCallback 在接口中 RemoteCallback

getErrMsg

public String getErrMsg()
