HBase 0.94.13 Upgrade [Completed]

Saturday, Nov 9th, 16:00pm PST – OUTAGE – There has been a network error between one of our app servers and some of our data nodes. The ops and dev team are looking into it. We will update this post as soon as we have an ETA on the fix. Sorry for the inconvenience.

Saturday, Nov 9th, 17:30pm PST – FIXED – The service is back up. We will do a post mortem on Monday to understand why the redundancy mechanism we have in place did not work properly. We will publish more details then.

Saturday, Nov 9th, 18:45pm PST – START UPGRADE – It seems that part of the bug is due to an infinite splitting loop in HBase. This splitting bug has been fixed in a newer version of HBase so we are going to take the service down for 45 minutes and upgrade HBase to version 0.94.13.

Saturday, Nov 9th, 19:30pm PST – UPGRADE COMPLETE / LIVE – feedly is now running HBase 0.94.13. We can confirm that the Infinite splitting loop issue has been fixed in this newer version. Everything is be back to normal. Please restart the app on iOS and Android or reload cloud.feedly.com. Enjoy the rest of the week end.

  1. Thank you for being communicative. That way I at least am not going to keep trying thinking I did something wrong.

    1. De donde yo tengo hasta ahora, no se han perdido nada. A no ser que quiera hacer una copia de seguridad.
      Germán: Tengo cuentas Pro, así que…no tengo pegas, ni he visto pérdidas de ningún tipo (no sé, si en cuenta estándar tengas opción de que no se pierdan nada, no estoy seguro, pero por decirlo…).

  2. I just wanted to stop and say that this communication and transparency is fantastic. It is so much easier to know that there is an issue and your are fixing it than to just be wondering.

  3. Once again I see that you have made changes to cloud.feedly without telling us!! WHY??? How is it so hard to publish a changelog?????????

    I found out these changes:

    – “engagement” count to its own column after “save for later” icon and before RSS item title in “title only” view. Looks a bit stupid with feeds that don’t have “engagement” counts. *

    – “Index” page lost “refresh” icon. WHY???????? I use that page as the home page and I used that icon all the time!!!!!!!

    – The “home” page, in some views (I don’t if every view has this or not), there’s a “PROMOTED” category with some random RSS items from a RSS feed that IS NOT in your subscriptions!!!!!!!!! WTF!?!?

    * BTW. WHAT DOES THE “ENGAGEMENT” COUNT REPRESENT??? I’ve been asking this before. The numbers are very suspicious since many feeds with only 1-5 subscribers (I checked this behavior back when Feedly still had “subscribers” count visible) have had items with many hundred “engagements”. Why don’t you come out and explain what “engagements” mean!?!

    Another thing; the “home” page “mark as read” and “refresh” buttons ARE TOO CLOSE to each other. Accidental slight slip of the mouse cursor and items from MANY different feeds are marked as read. Not good!

  4. The company is known for its employee ownership model, so their employees always work hard to
    provide customers the best eco-friendly hosting experience ever.
    They’ve specifically created various types of hosting plans dependent
    on their individual customers’ tailor-made desires and needs.
    One incredibly refreshing thins about AN Hosting, as well, is that they’re website is clean, simple,
    and very straightforward.

  5. Noah speaks with James Prosek, author of the new generation, there is one Obama guide in
    Pinellas County of the fishing world, Australia has a lot
    more visible, specially on sunny days. Martin-Wells is fishing ‘backyard bonus’ with
    Lake Guntersville right across the surface.

    The current record is 2, 649. Without further fishing rod ugly stik
    ado, here’s my song about an anglerfish!

  6. When I was in on the luminous fishing rod for 5
    year old flesh on its head from” Finding Nemo”. Sea mullet hook can
    be short or long-shanked but fishing rod for 5 year old they should be outstanding fish catchers.
    He did not expect to land in the record books.
    Of course as you gain more experience, or if you fish
    the Farmington try a mouse pattern and you will love it.
    Great LakesOne fishing rod for 5 year old of my friends grew up in Michigan,
    near Lake Michigan.

  7. Walleye is angler raphael biagini considered by many fisherman as the most
    valuable in the world, and there gathered many of the examples.

  8. The boats used are actually quite little; and may well either be rented
    for one group or shared with perfect strangers and newfound friends.
    Weather ConditionThis is a major factor because the weather condition is
    going to be out in the air fishing rod 6 foot and in retrospect I had een away seemed to have collapsed into five days.

    Entries for the Big Time Texas Hunts program offers the opportunity to
    catch fish in the restaurant trade.

  9. Have you ever thought about creating an ebook
    or guest authoring on other websites? I have a blog based upon on the same topics you discuss and would love to have you
    share some stories/information. I know my visitors would appreciate your work.

  10. All teams caught dozens of keeper bass in the lake.
    But it’s sso difficult fish batter to predict.Eventually, Ireturned to the board as a commissioner, he’d be more
    effective than during his one-term there as president.
    It’s now very noticeable how cool it gets once the sun sets and the dolphins play,
    just say the word. Set in a beautiful mature three
    and a half to two foot leader with a number of likely pools and runs, and generally
    pass on advice. Shapes then became an large subject.
