Re: hbase pull request: 0.98

Is there a JIRA for this feature ? HBase hasn't migrated to git repository yet. Submitting patch is the preferred way of contribution. Cheers On Jan 16, 2014, at 10:06 PM, yuchao86 g...@git.apache.org wrote: GitHub user yuchao86 opened a pull request:

Re: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

Guys, Trying to benchmark on AWS is a waste of time. You end up chasing ghosts. You want to benchmark, you need to isolate your systems to reduce extraneous factors. You need real hardware, real network in a controlled environment. Sent from a remote device. Please excuse any typos... Mike

Re: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

I need to apologize and clarify this statement… First, running benchmarks on AWS is ok, if you’re attempting to get a rough idea of how HBase will perform on a certain class of machines and you’re comparing m1.large to m1.xlarge or m3.xlarge … so that you can get a rough scale on sizing.

Re: 答复: 答复: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

One other question: Did you give the RS the default 1000mb heap? For real work you have to increase that. Maybe try with 4000 or 8000 on those boxes. (In any case that will not solve any problem with unreachable or unavailable data nodes) -- Lars - Original Message - From: Vladimir

Re: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

I generally agree. However, the High I/O and Cluster Compute types are HVM single tenant on the server, and the IO stack uses SR-IOV so MMIO and interrupts are directly going to the VM, and 10GE network paths with no traffic but your own. The locally attached storage is SSD. This is pretty close

I just started ycsb on our real cluster: ./bin/ycsb load hbase -P workloads/load20m -p columnfamily=family -s -threads 100 -target 15000 This is beginning of a ycsb log on real grid run (looks even worse than on AWS): 10 sec: 150231 operations; 14984.14 current ops/sec; [INSERT

Re: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

You can also grep your logs for entries from JvmPauseMonitor. When you're trying to track down an anomaly, it can help you locate the ballpark of at least when it happened. Correlate it back into your Ganglia, OpenTSDB, CloudWatch, c systems and look for more info. I think it makes a statement

Re: HBase 0.94.15: writes stalls periodically even under moderate steady load (AWS EC2)

JvmPauseMonitor is not in 0.94 branch. Maybe HBASE-9630 should be backported to 0.94 ? Cheers On Fri, Jan 17, 2014 at 10:54 AM, Nick Dimiduk ndimi...@gmail.com wrote: You can also grep your logs for entries from JvmPauseMonitor. When you're trying to track down an anomaly, it can help you
