RE: Hyperthreading

Hi, I believe years ago when testing the precursor product to Trafodion, which included components not currently part of Trafodion, testing with Hyperthreading on encountered unexpected/different from HT off results (I’m not sure exactly what was encountered). Given how long ago that was,

RE: Trafodion environment changes

Hi, WRT to “hbase-site.xml: Change hbase.regionserver.region.split.policy to org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy”, I would imagine by now with the replies to your “Disable HBase Region Rebalancing” e-mail you can see how these two topics are related? Namely,

RE: Trafodion Runtime Security

Are you asking about accessing HDFS files or something else? If it’s the former then yes they do work. But just like with Linux files it all depends on having users in groups. Otherwise if hbase owns the files and trafodion isn’t part of the same group the access options are limited. That

Request for information about the installer's new management nodes prompt.

Hi, Some time back I noticed a new prompt as I was installing a Trafodion build: Do you have a set of management nodes (Y/N), default is N: I was wondering how to appropriately answer this prompt to use the new feature as it was intended. For example, one cluster is using the HA configurati

A failed Trafodion installation can lead to the hbase:meta table staying in the FAILED_OPEN state.

Hi, I ran into this situation during a recent installation and thought it might be useful if others were to hit a similar situation in the future. This isn't the only way to recover from the situation but it is one option and was proven to work as expected. Regards, Dennis During a recent Tr

RE: perl-DBD-SQLite*

Hi, I’m not a yum expert, but could the ‘*’ actually be part of a glob expression? For example on a CentOS 6.5 node I did: yum list installed "perl-DBD-SQLite*" … perl-DBD-SQLite.x86_64 1.27-3.el6

RE: 答复: A failed Trafodion installation can lead to the hbase:meta table staying in the FAILED_OPEN state.

Trafodion on CentOS 7.x: CPU usage differences--cosmetic change or an OS level change that can be used to improve system performance?

Hi, I know, this is the Trafodion user DL not a CentOS 7.x DL, but given an OS changes major versions months if not years before the next level software starts to use it, I assume Trafodion users will come looking here once CentOS 7.x is a supported version. I have had access to some prototy

Hi Amanda, I was a little surprised to see: Name: namenode_java_heapsize Value: 1GB (or 1073741824 bytes) Why: Still needed: I thought we discovered during some testing that doing this was actually causing the heapsize to be reduced from the 2GB on one system to 1GB? If that’
