Description

The output of the BeeLine tests is sometimes flaky, especially if the query is a fast one

The output is sometime this:

PREHOOK: query: select explode(array('a', 'b'))
PREHOOK: type: QUERY
PREHOOK: Input: _dummy_database@_dummy_table
#### A masked pattern was here ####
POSTHOOK: query: select explode(array('a', 'b'))
POSTHOOK: type: QUERY
POSTHOOK: Input: _dummy_database@_dummy_table
#### A masked pattern was here ####
a
b

Sometime this:

a
b
PREHOOK: query: select explode(array('a', 'b'))
PREHOOK: type: QUERY
PREHOOK: Input: _dummy_database@_dummy_table
#### A masked pattern was here ####
POSTHOOK: query: select explode(array('a', 'b'))
POSTHOOK: type: QUERY
POSTHOOK: Input: _dummy_database@_dummy_table
#### A masked pattern was here ####

Notice, that the actual query result is either before, or after the stuff printed by the hooks.
