[CARBONDATA-1351]When 'SORT_SCOPE'='GLOBAL_SORT' and 'enable.unsafe.câ¦
â¦olumnpage'='true', 'ThreadLocalTaskInfo.getCarbonTaskInfo()' return null
When 'SORT_SCOPE'='GLOBAL_SORT' and 'enable.unsafe.columnpage'='true', it
uses native RDD of Spark to load data, the method of
'ThreadLocalTaskInfo.setCarbonTaskInfo(carbonTaskInfo)' in
âCarbonRDD.computeâ does not be called, so
'ThreadLocalTaskInfo.getCarbonTaskInfo()' will return null in some unsafe
related classes, such as: UnsafeFixLengthColumnPage, UnsafeVarLengthColumnPage,
UnsafeMemoryDMStore and so on.
Solution: Set the CarbonTaskInfo in the method of
'ThreadLocalTaskInfo.getCarbonTaskInfo()' when 'threadLocal.get()' is null.
