------------------------------------------
Summary: NPE in RetryingMetaStoreClient#invoke when catching
MetaException with no message
Key: HIVE-23534
URL: https://issues.apache.org/jira/browse/HIVE-23534
Project: Hive
Issue Type: Bug
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
RetryingMetaStoreClient#invoke method catches MetaException and attempts to
classify it by checking the message. However there are cases (e.g., various
places in
[ObjectStore|https://github.com/apache/hive/blob/716f1f9a945a9a11e6702754667660d27e0a5cf4/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L3916])
where the message of the MetaException is null and this leads to NPE.
