-----------------------------------------
Summary: ObjectStore transaction handling can be simplified
Key: HIVE-17736
URL: https://issues.apache.org/jira/browse/HIVE-17736
Project: Hive
Issue Type: Improvement
Components: Hive
Affects Versions: 3.0.0
Reporter: Alexander Kolbasov
Assignee: Alexander Kolbasov
There are many places in ObjectStore that do something like this:
{code}
boolean commited = false;
try {
openTransaction();
commited = commitTransaction();
} finally {
if (!commited) {
rollbackTransaction();
}
}
{code}
We can simplify this in two ways:
1) Create a wrapper that calls given piece of code inside the block of code
above. This is similar to TransactionManager in Sentry.
2) Create a special auto-closeable object that does the check and rollback on
close.
