Srikanth Sundarrajan commented on FALCON-2104: ---------------------------------------------- I dont know of a way to distribute this outside a release. I would think it is best shipped as a part of 0.10 release. > Loss of data in GraphDB when upgrading Falcon from 0.9 to 0.10. > ---------------------------------------------------------------- > > Key: FALCON-2104 > URL: https://issues.apache.org/jira/browse/FALCON-2104 > Project: Falcon > Issue Type: Bug > Affects Versions: 0.10 > Reporter: Balu Vellanki > Assignee: Balu Vellanki > Priority: Critical > Fix For: trunk, 0.10 > > Original Estimate: 48h > Remaining Estimate: 48h > > FALCON-1333 (Instance Search feature) requires Falcon to use titan-berkeleyje > version 0.5.4 to support indexing. Up until version 0.9 - Falcon used > titan-berkeleyje-jre6 version 0.4.2. GraphDB created by version 0.4.2 cannot > be read by version 0.5.4. When attempting an upgrade, I realized that entity > and instance lineage data created in 0.9 version could not be read by Falcon > in 0.10 version. > The only solution seems to provide a tool to do the following > - Use 0.4.2 version of titan-berkeleyje-jre6 to read the berkeleyDB based > graphDB and create a JSON file with all data. > - shutdown falcon-0.9, upgrade Falcon. > - use 0.5.4 version of titan-berkeleyje to read JSON file and repopulate > berkeleyDB based graphDB. > - restart falcon-0.10 > I will work on the tool, and update release-notes, upgrade instructions > accordingly. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
