Hi all, The only thing you need to do to run an 0.90 release is to sub out the hadoop-core jar with the one from your version of CDH. The issue isn't the security stuff (which we now shim on the hbase side, thanks to the Trend guys!) but rather a different protocol version number for the data transfer protocol.
Of course once a final 0.90 release is out, we'll have a CDH release off this tree which "just works" -Todd On Wed, Dec 22, 2010 at 3:56 AM, Friso van Vollenhoven < [email protected]> wrote: > If you do not enable any of the security features in CDH3b3 or another > flavor of secure Hadoop, it should just work, right? > > Friso > > > > On 22 dec 2010, at 11:16, Andrew Purtell wrote: > > > Bill, > > > > I believe using CDH3B*2* will get you what you want. > > > > ASF HBase 0.90 will not be compatible with secure versions of Hadoop, > which includes CDH3B3. > > > > Best regards, > > > > - Andy > > > > Problems worthy of attack prove their worth by hitting back. > > - Piet Hein (via Tom White) > > > > > > --- On Tue, 12/21/10, Bill Graham <[email protected]> wrote: > > > >> From: Bill Graham <[email protected]> > >> Subject: Re: provide a 0.20-append tarball? > >> To: [email protected], [email protected] > >> Cc: [email protected] > >> Date: Tuesday, December 21, 2010, 11:41 PM > >> Hi Andrew, > >> > >> Just to make sure I'm clear, are you saying that HBase 0.90.0 is > >> incompatible with CDH3b3 due to the security changes? > >> > >> We're just getting going with HBase and have been running 0.90.0rc1 on > >> an un-patched version of Hadoop in dev.
