Impala incorrectly returned NULLs in the "Max Size" column of the SHOW COLUMN STATS result when executed through the HS2 interface. The issue was that the column was specified to be type INT in the result schema, but the actual type of the contents that we inserted into it was "long". The reason why this is not an issue in Impala shell is because we stringify the contents without inspecting the metadata for beeswax results. The issue was fixed by changing the type from INT to BIGINT.
