Re: Regions Stuck PENDING_OPEN

First off: You're on EMR? What version of HBase you're using? (Maybe Zach or Stephen can help here too). Can you figure out the RegionServer(s) which are stuck opening these PENDING_OPEN regions? Can you get a jstack/thread-dump from those RS's? In terms of how the system is supposed to work:

Re: Master-Master Replication problem in hbase2.0

Please do not cross-post lists. I've dropped dev@hbase. This doesn't seem like a replication issue. As you have described it, it reads more like a data-correctness issue. However, I'd guess that it's more related to timestamps rather than be an issue on your cluster. If there was no error,

Re: HMerge Status

not mistaken the Normalizer will keep the same number of regions, but will uniform the size, right? So if the goal is to reduce the number of region, the Normalizer might not help? JMS Le ven. 31 août 2018 à 09:16, Josh Elser a écrit : There's the Region Normalizer which I'd presume would

Re: HConnection in TIMED_WATING

That thread is a part of the ThreadPool that HConnection uses and that thread is simply waiting for a task to execute. It's not indicative of any problem. See how the thread is inside of a call to LinkedBlockingQueue#poll() On 9/28/18 3:02 AM, Lalit Jadhav wrote: While load testing in the

Re: HBase-Connectors Library on Maven

Hi Davis, I don't think we have a release planned yet for the hbase-connectors library. I know our mighty Stack has been doing lots of the heavy lifting around lately. If you're interested/willing, I'm sure we'd all be gracious if you have the cycles to help out testing what we have in the

Re: HBase connection refused after random time delays

Looks like your RegionServer process might have died if you can't connect to its RPC port. Did you look in the RegionServer log for any mention of an ERROR or FATAL log message? On 4/4/19 8:20 AM, melank...@synergentl.com wrote: I have installed Hadoop single node
