> In case of compaction, queryExecutor object is formed for multiple blocks but
> the objects are not retained and finish method is called only on the last
> instance created for query executor. Due to this the memory allocated to
> precious objects is not released which can lead to out of memory issue.
> Steps to reproduce:
> ----------------------------------
> CREATE TABLE IF NOT EXISTS t3 (ID Int, date Date, country String, name
> String, phonetype String, serialname char(10), salary Int) STORED BY
> 'carbondata' TBLPROPERTIES('DICTIONARY_EXCLUDE'='name')
> LOAD DATA LOCAL INPATH 'data.csv' into table t3
> LOAD DATA LOCAL INPATH 'data.csv' into table t3
> alter table t3 compact 'major'
