             Summary: hadoop version < 3.2 throw IllegalAccessError when assign proxy
                 Key: HDDS-3560
                 URL: https://issues.apache.org/jira/browse/HDDS-3560
             Project: Hadoop Distributed Data Store
          Issue Type: Bug
          Components: om, Ozone Client
    Affects Versions: 0.6.0
            Reporter: maobaolong
            Assignee: maobaolong


The method createOMProxyIfNeeded of OMFailoverProxyProvider will throw IllegalAccessError when work with hadoop version lower than 3.2. 

The following is the problem code, it want assign a proxy to `proxyInfo.proxy`.
{code:java}
  private void createOMProxyIfNeeded(ProxyInfo proxyInfo,
      String nodeId) {
    if (proxyInfo.proxy == null) {
      InetSocketAddress address = omProxyInfos.get(nodeId).getAddress();
      try {
        proxyInfo.proxy = createOMProxy(address);
      } catch (IOException ioe) {
        LOG.error("{} Failed to create RPC proxy to OM at {}",
            this.getClass().getSimpleName(), address, ioe);
        throw new RuntimeException(ioe);
      }
    }
  }
{code}

But,  hadoop lower than 3.2, the field proxy of proxyInfo is marked as final. 

{code:java}
public static final class ProxyInfo<T> {
    public final T proxy;
    /*
     * The information (e.g., the IP address) of the current proxy object. It
     * provides information for debugging purposes.
     */
    public final String proxyInfo;
    ...
}
{code}

So, if we want to work around, we should  catch the exception and new a ProxyInfo instance instead.
