Review comment:
Without this change. The CI throws the exceptions (checked in serveral
different envs):
java.lang.RuntimeException: Store location not set for the key
__temptable-f8c5bbbf-0b73-4288-9438-146283d442c0_1592586283728_null_e8112868-3cf4-442d-bf9c-05f90bfca8240x0
at
org.apache.carbondata.processing.loading.TableProcessingOperations.deleteLocalDataLoadFolderLocation(TableProcessingOperations.java:125)
The root cause is
the line: "val context = new TaskAttemptContextImpl(**confB**, attemptID)"
different context will have the same taskno, which is strange.
With this line, the exception disappears, CI passed.
