Per I know: 1.zookeeper is sensitive to resources(Memory, Disk, CPU, NetWork). If there is some underprovisioning on server, then a) Server may not respond to client requests in time. b) Client assumes server is down, closes the socket and it connects to other server.
2. Hbase is sensitive to RAM. But CPU use less. 3. M/R(it againsts HDFS ) is sensitive to CPU and Memory. My question is that: 1. Does it have a race resource between HDFS, ZK, M/R and Hbase? 2. Suppose that one machine fault, the cluster should be safe. What do I need consider(eg: cpu, network use rate or configure)? 3. Is there anyone who has used below configure for product? -----邮件原件----- 发件人: [email protected] [mailto:[email protected]] 代表 Stack 发送时间: 2011年6月1日 4:13 收件人: [email protected] 主题: Re: about disposing Hbase process Sorry Gao, what is your question?
