---------------------------------------
[~ashutoshc]
The src_thrift table is
aint int from deserializer
astring string from deserializer
lint array<int> from deserializer
lstring array<string> from deserializer
lintstring
array<struct<myint:int,mystring:string,underscore_int:int>> from
deserializer
mstringstring map<string,string> from deserializer
and when i run
query: ANALYZE TABLE src_thrift COMPUTE STATISTICS
it threw exception
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.ColumnStatsTask
The main reason is that in ObjectStore.java, validateTableCols function,
table.getSd().getCols() returns null.
The primitive table was there after the data/scripts/q_test_init.sql is
executed.
But the primitive table and (dest1,2,3,4 tables) disappeared right before I run
any q test. The partition column status of primitive table are there. I could
not find the code where primitive table is dropped/deleted.

> Current q_test only generates tables, e.g., src only but does not create
> status. All the test cases will fail in CBO because CBO depends on the
> status.
