Change subject: WIP IMPALA-12896: Avoid JDBC table to be set as transactional table ...................................................................... WIP IMPALA-12896: Avoid JDBC table to be set as transactional table In some deployment environment, JDBC tables are set as transactional tables by default. This causes catalogd failed to load the metadata for JDBC tables. This patch explicitly add table properties with "transactional=false" for JDBC table to avoid the JDBC to be set as transactional table. The operations on JDBC table are processed only on coordinator. The processed rows should be estimated as 0 for DataSourceScanNode by planner so that coordinator-only query plans are generated for simple queries on JDBC tables and queries could be executed without invoking executor nodes. Updates FileSystemUtil.copyFileFromUriToLocal() function to write log message for all types of exceptions. Testing: - TODO: update planer tests for data source tables. - TODO: pass core -tests.
