> We found that [BackendConfig.INSTANCE|https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/ResetMetadataStmt.java#L265] could be null in the frontend test [testResetMetadataDesc()|https://github.com/apache/impala/blob/master/fe/src/test/java/org/apache/impala/util/CatalogOpUtilTest.java#L65] and thus [ResetMetadataStmt#toThrift()|https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/ResetMetadataStmt.java#L265] could fail with the following error.
> {code}
