Expand exceptions caught for metastore operations
-------------------------------------------------
Key: HIVE-2002
URL: https://issues.apache.org/jira/browse/HIVE-2002
Project: Hive
Issue Type: Improvement
Components: Metastore
Affects Versions: 0.8.0
Reporter: Paul Yang
Priority: Minor
Currently, HiveMetaStore.executeWithRetry() catches two classes of exceptions
and retries the metastore call when such exceptions occur. However, it does not
catch some exceptions that could benefit from a retry:
{code}
Failed with exception javax.jdo.JDOException: Couldnt obtain a new sequence
(unique id) : The MySQL server is running with the --read-only option so it
cannot execute this statement
NestedThrowables:
java.sql.SQLException: The MySQL server is running with the --read-only option
so it cannot execute this statement
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.MoveTask
{code}
In this case, the MySQL server could be temporarily in a read-only mode, and a
later DB call may succeed. To handle these situations, this JIRA proposes to
expand the class of exceptions caught for retries.
