大早上剛到公司就發(fā)現(xiàn)報(bào)警，磁盤容量告警，zookeeper集群服務(wù)器報(bào)警。
二、處理過程
查看磁盤空間
df -h
2.確認(rèn)那個目錄占用空間比較多，發(fā)現(xiàn)是zookeeper
修改zookeeper參數(shù)文件（版本3.4.6）
vi zoo.cfg
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=20 #保留log和snapshot各20個
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1 #每小時清理一次
3.查看狀態(tài)
$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh status
JMX enabled by default
Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg
Mode: leader
4.關(guān)閉服務(wù)
$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh stop
JMX enabled by default
Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg
Stopping zookeeper ... STOPPED
5.重啟服務(wù)
$ /usr/local/RoilandGroup/zookeeper/bin/zkServer.sh start
JMX enabled by default
Using config: /usr/local/RoilandGroup/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
[hadoop@host-10-60-40-37 conf]$ jps

6.zookeeper集群中每一個節(jié)點(diǎn)都需要修改參數(shù)文件，然后重啟服務(wù).
至于為什么這么修改，是否還有其他的方式，大家可以看官方文檔，或者比較懶就百度。
7.理解每一個參數(shù)文件，看注釋就行
less zoo.cfg
# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/data/zookeeper
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
autopurge.snapRetainCount=20
# Purge task interval in hours
# Set to "0" to disable auto purge feature
autopurge.purgeInterval=1
