hiveserver2 java heap space

[Patcharee Thongtra]

Hi,

I tried to query orc file by beeline and java program using jdbc 
("select * from orcfileTable limit 1"). Both failed with Caused by: 
java.lang.OutOfMemoryError: Java heap space. Hiveserver2 heap size is 
1024m. I  guess I need to increase this Hiveserver2 heap size? However I 
wonder why I got this error because I query just ONE line. Any ideas?

Thanks,

Patcharee
