Hive does not support literals for complex types (array, map, struct, union), so it is not possible to use them in INSERT INTO...VALUES clauses. This means that the user cannot insert data into a complex datatype column using the INSERT INTO...VALUES clause. link

In hive explicit LOCATION is just a pointer.

I am trying to switch to Beeline from hive, but I have one issue.
Hive :
Query : select * from table; Output : The output is in readable format i.e we can scroll down to see complete data on my screen(terminal).
Beeline :
Query : select * from table; Output : The output is not in readable format i.e we cannot scroll down to see complete data. All columns are mixed up. Work Around :
I tried setting --maxWidth=100 it worked for one table with 10 columns. But still the output is not properly readable. I have to change the value of maxWidth for different tables as different tables have different number of columns.
So, is there any way to set some default value so that the data becomes understandable using beeline?

I am trying to pass a WHERE condition as a variable to hive hql via BeeLine. --hivevar somekey1='"someValue"'
works well --hivevar somekey2='"colum1<=someValue"'
does not work which prints the Beeline usage. How can I escape equal to (=)? Any help or pointers on how I can solve this issue?
