Hi Carol, Thanks for putting together these charts and starting the discussion about supported versions. Once Trafodion supports Apache Hadoop/HBase, I question whether there is a reason to continue to support the Cloudera and HortonWorks distros.
Thanks, Atanu ----- *From:* Carol Pearson [mailto:carol.pearson...@gmail.com] *Sent:* Thursday, February 4, 2016 4:53 PM *To:* user@trafodion.incubator.apache.org *Subject:* Trafodion Release 2.0 Hadoop/HBase Versions? Hi Trafodion Fans, I'm trying to make sure I'm clear on the targeted runtime environments for our next release, which I think we're calling Trafodion 2.0. I've seen that it needs to support working with Apache Hadoop, since the 1.3 release supported only the Cloudera and Hadoop distros. *Trafodion 2.0* >From what's been discussed on the Dev list and here, I think the target is: - Linux Versions CentOS 6.5-6.7 (RHEL 6.5-6.7 - untested? but should support) - SUSE? Hadoop/Version HBase Version ========================================= Cloudera CDH 5.4.x 1.1 Hortonworks HDP 2.3 1.1 Apache Hadoop 2.7.1 1.1 Are these the targets that folks are working on Trafodion 2.0 to support? Are they the right ones? (For example, should we be looking at Apache Hadoop 2.6.3?) Are there other versions of software in the Hadoop ecosystem whose versions should be specified as targets, especially for distro-less vanilla Apache Hadoop? I think that once we release, we should identify the specific versions that folks have tested with (which might not be all versions and all distros). I think we should also list versions for software that we believe should work but have not been tested. As I was trying to understand which releases worked with what, I came across a great chart in the the HBase reference book in section 4.1: https://hbase.apache.org/book.html#basic.prerequisites then scroll down to see the Hadoop versions. It would be great to develop that chart for Trafodion as 2.0 goes forward. Thanks for any light people can shed on this! -Carol P. PS: For reference, here's my understanding of what Trafodion 1.3 supported: I've put together the following chart based on the notes from the Trafodion website for release 1.3 and my understanding of Trafodion 2.0: *Trafodion 1.3: (Current release)* - Linux Versions: CentOS 6.5-6.7, (RHEL 6.5-6.7 - untested? but should support) Hadoop/Version HBase Version ========================================= Cloudera CDH 5.3.x 0.98 Hortonworks HDP 2.2 0.98 --------------------------------------------------------------- Email: carol.pearson...@gmail.com Twitter: @CarolP222 --------------------------------------------------------------- ____________________ Atanu Mishra
