Thanks for the response Qifan... but I am not sure we are talking about the same thing.
I am talking about the traf_<hadoop distro>_mods98 script that is run as apart of the Trafodion Installation scripts. It is used to setup HBase settings, copy hbase-trx*.jar file, and restart HBase, HDFS, and Zookeeper. I would like to know what are the smallest number of settings that need to be set in advance for Trafodion to install/start. Examples of things set: hbase-site hbase.master.distributed.log.splitting false hbase-site hbase.coprocessor.region.classes "org.apache.hadoop.hbase.coprocessor.transactional.TrxRegionObserver,org.apache.hadoop.hbase.coprocessor.transactional.TrxRegionEndpoint,org.apache.hadoop.hbase.coprocessor.AggregateImplementation" hbase-site hbase.hregion.impl org.apache.hadoop.hbase.regionserver.transactional.TransactionalRegion hbase-site hbase.regionserver.region.split.policy org.apache.hadoop.hbase.regionserver.ConstantSizeRegionSplitPolicy hbase-site hbase.snapshot.enabled true hbase-site hbase.bulkload.staging.dir /hbase-staging hbase-site hbase.regionserver.region.transactional.tlog true hbase-site hbase.snapshot.master.timeoutMillis 600000 hbase-site hbase.snapshot.region.timeout 600000 hdfs-site dfs.namenode.acls.enabled true hbase-site hbase.client.scanner.timeout.period 600000 Thanks all!
