----------------------------------------
Summary: Fixed OOM in case of complex type
Key: CARBONDATA-2464
URL: https://issues.apache.org/jira/browse/CARBONDATA-2464
Project: CarbonData
Issue Type: Improvement
Reporter: kumar vishal
Assignee: kumar vishal
Problem: Query with Complex type is failing with OOM
Root Cause: Complex type child column(No-dictionary) values are written in LV
format, while reading the data it will read length then based on length it is
reading the data. Converting byte array to int is giving wrong length value,
because of this it's trying to create big memory chunk and as memory is not
available in Unsafe it is failing with OOM.
Code issue: While converting byte array to int it is not masking the the byte
values and because of this is giving wrong integer value.
Solution: Mask each byte and then left shift the bits
