----------------------------------

             Summary: [Java] How to use RootAllocator in a low memory setting?
                 Key: ARROW-6500
                 URL: https://issues.apache.org/jira/browse/ARROW-6500
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
    Affects Versions: 0.13.0
            Reporter: Andong Zhan


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/cacertsPicked up JAVA_TOOL_OPTIONS: -Djavax.net.ssl.trustStore=/etc/pki/ca-trust/extracted/java/cacertsException in thread "main" java.lang.ExceptionInInitializerError at org.apache.arrow.memory.BaseAllocator.createEmpty(BaseAllocator.java:263) at org.apache.arrow.memory.BaseAllocator.<init>(BaseAllocator.java:89) at org.apache.arrow.memory.RootAllocator.<init>(RootAllocator.java:34) at org.apache.arrow.memory.RootAllocator.<init>(RootAllocator.java:30) at com.snowflake.TestArrow.main(TestArrow.java:13)Caused by: java.lang.NullPointerException at io.netty.buffer.PooledByteBufAllocatorL$InnerAllocator.<init>(PooledByteBufAllocatorL.java:145) at io.netty.buffer.PooledByteBufAllocatorL.<init>(PooledByteBufAllocatorL.java:49) at org.apache.arrow.memory.AllocationManager.<clinit>(AllocationManager.java:61) ... 5 more
Process finished with exit code 1
{code}
So how to use RootAllocator in such low memory case?
