Vertica adapter doesn't use explicity transactions or report progress
---------------------------------------------------------------------
Key: MAPREDUCE-1368
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1368
Project: Hadoop Map/Reduce
Issue Type: Bug
Affects Versions: 0.21.0
Reporter: Omer Trajman
Assignee: Omer Trajman
Fix For: 0.21.0
The vertica adapter doesn't use explicit transactions, so speculative tasks can
result in duplicate loads. The JDBC driver supports it so the fix is pretty
minor. Also the JDBC driver commits synchronously and the adapter needs to
report progress even if it takes longer than the timeout.
