Re: Rows per second for RegionScanner

Try disabling block encoding - you will get better numbers. >> I mean per region scan speed, Scan performance depends on # of CPU cores, the more cores you have the more performance you will get. Your servers are pretty low end (4 virtual CPU cores is just 2 hardware cores). With 32 cores per

Re: Rows per second for RegionScanner

hi Thakrar Thanks for your reply. My settings for the RegionScanner Scan is scan.setCaching(1024) scan.setMaxResultSize(5M) even if I change the caching to 10 I'm still not getting any improvements. I guess the caching works for remote scan through RPC, however not helping too much for

Hbase row key to Hive mapping

Hi, I'm storing the row key as following combination in bytes. Row key using rowbuilder: unused8+timestamp(int)+accountid(long)+id(long) When I'm trying to map that key in hive table, I'm unable to convert back the actual value since it's stored in bytes. Even I set mapping as :key#b. Please

Re: new 4.x-HBase-1.1 branch

Makes sense to drop the branch for HBase-1.0.x. I had proposed it here before: http://search-hadoop.com/m/9UY0h2XrnGW1d3OBF1=+DISCUSS+Drop+branch+for+HBase+1+0+ Enis On Thu, Apr 21, 2016 at 8:06 AM, Andrew Purtell wrote: > HBase announced at the last 1.0 release

Re: Can not connect local java client to a remote Hbase

Are you using hbase 1.0 or 1.1 ? I assume you have verified that hbase master is running normally on master-sigma. Are you able to use hbase shell on that node ? If you check master log, you would see which node hosts hbase:meta On that node, do you see anything interesting in region server log

Can not connect local java client to a remote Hbase

Re: new 4.x-HBase-1.1 branch

HBase announced at the last 1.0 release that it would be the last release in that line and I think we would recommend any 1.0 user move up to 1.1 or 1.2 at their earliest convenience. FWIW Also, as RM of the 0.98 code line I am considering ending its (mostly) regular release cadence at the end

RE: Rows per second for RegionScanner

Just curious - have you set the scanner caching to some high value - say 1000 (or even higher in your small value case)? The parameter is hbase.client.scanner.caching You can read up on it - https://hbase.apache.org/book.html Another thing, are you just looking for pure scan-read performance

Rows per second for RegionScanner

​Hi, experts, I'm trying to figure out how fast hbase can scan. I'm setting up the RegionScan in a endpoint coprocessor so that no network overhead will be included. My average key length is 35 and average value length is 5. My test result is that if I warm all my interested blocks in the block
