    [ https://issues.apache.org/jira/browse/TEZ-1450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14101545#comment-14101545 ] 

Siddharth Seth commented on TEZ-1450:
-------------------------------------

{code}
+   * master. Expert level configuration. Expert level setting.
{code}
Repeated Expert level.

COUNTER_CONFIGS - should mark them unstable. Also, they apply to individual tasks as well.

{code}
+  /**
+   * Int value. Specifies the number of times the app master may be retried in case of app master
+   * failure. Expert level configuration.
+   */
{code}
Would be clearer if this read - "total number of AM attempts" instead of retries.

{code}
public static final int TEZ_TASK_RESOURCE_CPU_VCORES_DEFAULT = 2;
{code}
OOB default should be low - I think 1 is good. This should be tweaked for clusters.

Rest looks good.
