OAP 1.0 cannot use Plasma Backend in docker Env when Plasma server and executor in different containers

[zhixingheyi-tian]

In OAP 1.0, Plasma Backend will use Simple Cache strategy when plasma-store-server is not running. So OAP 1.0 cannot use Plasma Backend in docker Env when Plasma server and executor in different containers.

def plasmaServerDetect(): Boolean = { val command = "ps -ef" #| "grep plasma" val plasmaServerStatus = command.!! if (plasmaServerStatus.indexOf("plasma-store-server") == -1) { logWarning("External cache strategy requires plasma-store-server launched, " + "failed to detect plasma-store-server, will fallback to simpleCache.") return false } true }

@winningsix @jikunshang, would you consider and implement this feature?
Thanks
