Re: What property would trigger a region split besides hbase.hregion.max.filesize ?

Ted, I'm using HBase 0.96.1.2.0.6.1 (HDP 2.0.6). I set the regionserver log level to *INFO*, so I did not find any log containing "SplitPolicy". I will set the log level to *DEBUG *and take a look at regionserver log later. Thanks Tao 2014-05-29 10:32 GMT+08:00 Ted Yu : > Which HBase relea

Re: Full stack rolling restart

Yes, a full-stack rolling upgrade is possible. To perform a full-stack rolling restart of the CDH platform, we added and tested that functionality through Cloudera Manager, starting in CM4, running CDH4 and onward. For HBase rolling upgrades, the only Cloudera-supported path is through Cloudera Man

Re: Full stack rolling restart

We have taken the approach of graceful stop of the RegionServer in maintenance. Then restarting the DataNode. Once it has registered and back online we start the RegionServer and move it's regions back. We do not compact before or after the operation since it takes a short period of time, and mi

Re: Full stack rolling restart

Restarting datanodes has been tricky for us from an HBase perspective. It always causes a bunch of timeouts and thus blips of service interruption. Perhaps the above JIRAs will help that, but it's hard to tell. I think the only truly safe way to do this with CDH4.x is: 1. Move all regions off re

Full stack rolling restart

I am curious to know what the industry folks think of rolling restart on the full stack. Envisioning something like each node which services it runs, stop all services, use new configs and start all services. Is it feasible to do this ? Can folks who have tried, share their experiences please? Tha
