---------------------------------
Summary: fix the bug that sql query row count is less than the
actual row count of the table
Key: LIVY-565
URL: https://issues.apache.org/jira/browse/LIVY-565
Project: Livy
Issue Type: Bug
Components: Server
Reporter: holmes.infra
For example, there is a table with two columns ,which has two hundred rows ,and
one of the column's data is all null .When the maxRows of sql query is 200 ,it
will only return 100 rows.The cause is that the ColumnBuffer array ,only
expands automatically when the inserted data size exceeds 100 , but does not
expand if the one of column data is all null.
