> NPE in TezClientUtils when "yarn.resourcemanager.zk-address" is present in
> Configuration
> ----------------------------------------------------------------------------------------
>
> Key: TEZ-3874
> URL: https://issues.apache.org/jira/browse/TEZ-3874
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.9.1
> Reporter: Eric Wohlstadter
> Assignee: Eric Wohlstadter
> Priority: Blocker
> Attachments: TEZ-3874.1.patch, TEZ-3874.3.patch, TEZ-3874.4.patch,
> TEZ-3874.5.patch, TEZ-3874.patch.2
>
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> "yarn.resourcemanager.zk-address" is deprecated in favor of
> "hadoop.zk.address" for Hadoop 2.9+.
> Configuration base class does't auto-translate the deprecation. Only
> YarnConfiguration applies the translation.
> In TezClientUtils.createFinalConfProtoForApp, a NPE is throw if
> "yarn.resourcemanager.zk-address" is present in the Configuration.
> {code}
> for (Entry<String, String> entry : amConf) {
> PlanKeyValuePair.Builder kvp = PlanKeyValuePair.newBuilder();
> kvp.setKey(entry.getKey());
> kvp.setValue(amConf.get(entry.getKey()));
> builder.addConfKeyValues(kvp);
> }
> {code}
> Even though Tez is not specifically looking for the deprecated property,
> {{amConf.get(entry.getKey())}} will find it during the iteration, if it is in
> any of the merged xml property resources.
> {{amConf.get(entry.getKey())}} will return null, and {{kvp.setValue(null)}}
> will trigger NPE.
> Suggested solution is to change to:
> {code}
> YarnConfiguration wrappedConf = new YarnConfiguration(amConf);
> for (Entry<String, String> entry : wrappedConf) {
> PlanKeyValuePair.Builder kvp = PlanKeyValuePair.newBuilder();
> kvp.setKey(entry.getKey());
> kvp.setValue(wrappedConf.get(entry.getKey()));
> builder.addConfKeyValues(kvp);
> }
> {code}
