最近搭建了一個(gè)storm環(huán)境，發(fā)現(xiàn)在提交一個(gè)topology之后，supervisor總是會(huì)無緣無故的死掉，日志如下

++++++++++++++++++++++++++++++++++++++++++++++++++++++++

根據(jù)日志追查代碼，發(fā)現(xiàn)at backtype.storm.utils.Utils.downloadFromMaster(Utils.java:361) ~[storm-core-0.10.0.jar:0.10.0]從中

可是給出的default.yaml樣例配置文件中根本沒有"nimbus.host"的配置，給出的是"nimbus.seeds"

?沒有辦法，不知道取舍哪一個(gè)，之后兩個(gè)都配上

nimbus.host : "10.211.55.13"

nimbus.seeds: "10.211.55.13"

結(jié)果一試，supervisor守護(hù)進(jìn)程，不在死掉了，storm程序提交成功，運(yùn)成功！！！困擾了好幾天的問題終于解決！！！
