J-D Could you please share some #s? like how many requests @ peak, data store size, # of nodes in cluster, etc (if u can reveal that is)?
I'm also planning to use HBase for realtime web app. I would like to get some inputs on what to do if something goes wrong... ..In development, if i see any issues, I do kill -9/stop all & rm -rf disk. due to time crunch ..(bad idea)..Obviously i can't do that in production.. -> Have you ever run into data corruption? ..that you could not recover any data? -> If there is outage & if if you have to restart servers, what order you restart servers? (I presume namenode/datanode, followed by HMaster, HRegionServer, followed by zookeper, followed by HBase client app) -> Is there anything that we must backup in the advent of outage? (or) let HDFS replication do its magic? ..I'm ok with losing few days data ..but not all. thanks in advance venkatesh -----Original Message----- From: Jean-Daniel Cryans <[email protected]> To: [email protected] Sent: Sat, Jul 10, 2010 1:47 pm Subject: Re: real world usage, any web applications built using hbase? At stumbleupon, we have su.pr (url shortner / advertising platform) that's totally based on HBase and has been in production for more than a year. Also many other parts of our main product also rely on HBase.
