Re: Deleting and cleaning old snapshots exported to S3

2017-11-22 Thread Timothy Brown
Hi Lex, We had a similar issue with our S3 bucket growing in size and we wrote our own cleaner. The cleaner first looks at the HFiles required by the current snapshots. We then figure out which snapshots we no longer want (for example snapshots older than a week or whatever rules you want). Then

StochasticLoadBalancer questions

2017-01-11 Thread Timothy Brown
Hi, I have a couple of questions about the StochasticLoadBalancer. 1) In CostFromRegionLoadFunction.getRegionLoadCost the cost is weights later samples of the RegionLoad more than previous ones. For example, with a queue size of 4 it would be (.5 * load1 + .25*load2 + .125*load3 + .125*load4).

High CPU utilization by meta region

2016-11-21 Thread Timothy Brown
Hi, We are seeing about 80% CPU utilization on the Region Server that solely serves the meta table while other region servers typically have under 50% CPU utilization. Is this expected? Here's some more info about our cluster: HBase version 1.2 Number of regions: 72 Number of tables: 97 Approx.
