Re: Using KnoxSSO Proxy for Hbase Web UIs

So if I'm understanding correctly, I've done something very similar to this before. You can setup a cross-domain trust at the server level. Then for your clients, you can specify the krb5 at bootup of java/kinit either through an environment variable or something like this:

Re: RPC calls in hbase

Disclaimer: this is what I think I know and I'm not an HBase contributor... Anytime we get scanner timeouts like that, we first expand the timeout itself like you're doing to fix the short-term problem. But then we look at our rowkey design and what we're doing. Timeouts like that are usually

Re: Zookeeper too many connections when using co-processor

Did you try upping the connections to 100 or so? We turned the max client connections off and haven't really noticed any detriments to that yet and we've been running some really big jobs with only 3 zk nodes... William Watson Lead Software Engineer On Thu, Mar 3, 2016 at 12:18 PM, Arul

Re: Full table scan cost after deleting Millions of Records from HBase Table

Region Server Start Failure

I added a region server process to an existing cluster node that didn't previously have a region server process and I'm getting a weird error (see stack traces below). I'm using HDP 2.1, HBase 0.98.0.2.1.7.0-784-hadoop2, hadoop 2.4.0.2.1.7.0-784. All the other 6 region servers are up without
