Handle table property changes.
Handle table property changes.
How Shark-specific changes are handled:
- "shark.cache":
If the value evaluated by CacheType#shouldCache() is true
, then create a SparkLoadTask to
load the Hive table into memory.
Set it as a dependent of the Hive DDLTask. A SharkDDLTask counterpart isn't created because
the HadoopRDD creation and transformation isn't a direct Shark metastore operation
(unlike the other cases handled in SharkDDLSemantiAnalyzer). *
If 'false', then create a SharkDDLTask that will delete the table entry in the Shark
metastore.
