Anyone knows how to change the max\_file\_descriptors on windows? I built ES cluster on Windows and got following process information: "max\_file\_descriptors" : -1, "open\_file\_descriptors" : -1, What does “-1 mean? Is it possible to change the max file descriptors on windows platform? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
