Helping Spread the Word about Apachecon EU 2016
Hi Everyone I'm forwarding the following message on behalf of Rich Bowen and the Apachecon team === As you are aware, we are holding ApacheCon in Seville in November. While this seems like a long way away, it is critical that we get on people's calendar now, so that they can plan, get budget approval, and spread the word to their contacts. Here's how you can help. If you Tweet, please consider using some of the following sample tweets to get the word out:  * Save the date. #ApacheCon is coming to Seville, November 14-18 2016.   http://apachecon.com/  * Come join me at @ApacheCon in Seville in November. http://apachecon.com/  * #ApacheBigData is the best place to learn what's next in the world   of big data. November 14-16 in Seville http://apachecon.com/  * @TheASF is 300 projects strong and growing. Come learn about all of   them at @ApacheCon in Seville - http://apachecon.com/ Please follow @ApacheCon and @TheASF, and retweet mentions of ApacheCon, to spread the word. If you use other social media platforms, share the URLs of the events and their CFPs, to collect the broadest possible audience for our events, as well as getting the best content: * Big Data:*_ Website: http://events.linuxfoundation.org/events/apache-big-data-europe CFP: http://events.linuxfoundation.org/events/apache-big-data-europe/program/cfp *_ApacheCon:_* Website: http://events.linuxfoundation.org/events/apachecon-europe CFP: http://events.linuxfoundation.org/events/apachecon-europe/program/cfp And, finally, if your employer benefits from the work that we do at Apache, or is looking for the brightest software developers in the industry, encourage them to sponsor the event. Sponsorship is available at all levels. Have them contact e...@apache.org for a prospectus, and I'll make the right introductions. Sponsors in the past include ... well, everyone. You have to go pretty deep into the Forbes Technology list ( http://fortune.com/2015/06/13/fortune-500-tech/ ) to find a company that hasn't sponsored ApacheCon. I hope to see you in Seville! == Thanks Sharan
Re: How to get last one month of data from hbase table.
If you have a Thrift server running, you can use HappyBase ( https://happybase.readthedocs.io/en/stable/) to get a pretty nifty Python API. That along with using a scan with the TimestampFilter should get you what you want. -Dima On Thursday, July 14, 2016, Mahesh Sankaran wrote: > Hi all, > > My client wants last one month of data in hbase table. > I know we can export using timestamp range.

Re: How to get last one month of data from hbase table.
TimestampsFilter*. My bad. :) -Dima On Friday, July 15, 2016, Dima Spivak wrote: > If you have a Thrift server running, you can use HappyBase ( > https://happybase.readthedocs.io/en/stable/) to get a pretty nifty Python > API.

Re: Is it ok to store all integers as Strings instead of byte[] in hbase?

Does Replication Affect Write Performance On The Main Cluster
Hi, Don't have anything conclusive but I have seen some correlation where in very high write rate situation, the write rate can increase when major compaction or some other high CPU/network activity (for example we run some Spark jobs on our replica HBase cluster) stops happening on the replica cluster. Basically looks like the rate is lower when the replica cluster is busy with some other activity. I wanted to know if this totally anecdotal evidence is something I should look into or whether it is something well known in the community. Thanks in advance for any pointer or advice for someone relatively new to HBase. Saad
Re: Does Replication Affect Write Performance On The Main Cluster
Wish I had an answer for you.. This is relevant to our interests as well as I planned to run spark jobs on our slave cluster. If we don't hear conclusively on the list I will do some benchmarking in a dev environment and attempt to reproduce Best, Iain Sent from my iPhone > On Jul 15, 2016, at 5:01 PM, Saad Mufti wrote: > > Hi, > > Don't have anything conclusive but I have seen some correlation where in > very high write rate situation, the write rate can increase when major > compaction or some other high CPU/network activity (for example we run some > Spark jobs on our replica HBase cluster) stops happening on the replica > cluster.
