Hi, Hans

You replied really quickly.  :)
I think waiting for a few weeks is OK and I can read more Trafodion technical materials during this period.
Thanks very much for your reply and for the recommended materials.

Hi Donhoff,

Thank you for letting us know what you would like to do, that sounds great. I hope I can get to this in the next few weeks, but can't promise. Please let me know if that's going to be a problem for you. In the meantime I hope you can try another platform, for example the sandbox (https://wiki.trafodion.org/wiki/index.php/Installing_the_Trafodion_Sandbox).


Just FYI, this page (https://wiki.trafodion.org/wiki/index.php/Configuration#Installer_Modifications_to_HBase) shows some of the configuration changes that need to be done on a system, for Cloudera and Hortonworks those are performed by the installer.


Regards,


Hans

Hi, Hans

Thanks very much for your reply.

Our current plan is to verify Trafodion on a 4-nodes cluster first. If this succeeds, we will set it up on a production cluster environment to build an internet-based financial application. Since our cluster uses the Apache Hadoop/HBase, I have to consider installing Trafodion on Apache environment.

But according to your description, I think it would be better to wait for you guys to work out the documents and verify the exact steps first. Maybe my work will be easier after your work done.
Thanks again! :)

Hi,

Yes, it should be possible, but we are still working on documenting the exact steps and validating that there are no issues. Do you want to create a simple single-node setup or a cluster?


For a single node, the best way at the moment is probably by using the install_local_hadoop script, which can be found in core/sqf/sql/scripts. This script downloads the Hadoop, HBase and Hive jars and creates a sandboxed, single node installation in core/sqf/sql/local_hadoop. Note that there are a few files you may need to download manually, since they require accepting a license (e.g. MySQL and the file from the tpc.org site, which is non-essential).


What we haven't quite tried yet is to use pure Apache jars. Right now, the scripts downloads a jar from Cloudera, but hopefully replacing that with Apache objects won't be too difficult. We hope to do that step and publish the results in a few weeks.



For  multi-node cluster, we would need to verify that the installer program sets up the required HBase configuration files like hbase-site.xml correctly. If not, you would need to do these steps by hand for now.



Please let us know how it is working out for you or if there are any issues we can help with.


Hans

Hi,


On the web it is said that the trafodion should be installed on CDH or HDP. Is it possible to install trafodion on Apache Hadoop and HBase? If the answer is true, how to do it ? Many Thanks!
