Andong Zhan updated ARROW-6500:
-------------------------------
Description:
When I run this simple code with JVM setting: "-Xmx64m"
{code:java}
package com.snowflake;
import org.apache.arrow.memory.RootAllocator;
public class TestArrow
{
public static void main(String args[]) throws Exception
{
new RootAllocator(Integer.MAX_VALUE);
}
}
{code}
and got the following error
{code:java}
Picked up JAVA_TOOL_OPTIONS:
-Djavax.net.ssl.trustStore=/etc/pki/ca-trust/extracted/java/cacerts

... 5 more

{code}
So how to use RootAllocator in such low memory case?
