Sean Broeder resolved TRAFODION-2623. ------------------------------------- Resolution: Fixed First phase of porting is complete > Port Esgyn DTM changes to Trafodion > ----------------------------------- > > Key: TRAFODION-2623 > URL: https://issues.apache.org/jira/browse/TRAFODION-2623 > Project: Apache Trafodion > Issue Type: New Feature > Components: dtm > Affects Versions: 2.2-incubating > Reporter: Sean Broeder > Assignee: Sean Broeder > Fix For: 2.2-incubating > > > There are a very large number of changes present in the DTM components from > Esgyn that are not present in Trafodion. It is not practicable to cherry > pick these changes as the two environments are quite different and every > cherry pick attempt I tried involved complicated manual merges. As a > consequence, a large port of DTM changes en masse would be both easier > approach and also safer since the Esgyn code has been much more thoroughly > tested. > A sample of the fixes included are: > Dozens of bug fixes > Improved recovery after HBase failures > Better error reporting and tracing, which includes region keys for easier > debugging > Reduced UnknownTransactionExceptions resulting from duplicate transaction > registration > Better TLOG management including reducing the default number of tables > This is the first porting of Esgyn changes. There will need to be additional > , smaller porting effort. Ultimately the goal is to get the 2 DTM version > close enough that cherry picking will become normal and future mass portings > will not be necessary. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
