------------------------------------------
Summary: Make Number Of Tez AM Attempts Configurable When DAG
Recovery Is Disabled
Key: TEZ-4148
URL: https://issues.apache.org/jira/browse/TEZ-4148
Project: Apache Tez
Issue Type: Task
Reporter: Syed Shameerur Rahman
Assignee: Syed Shameerur Rahman
Currently when DAG recovery is set to false, The MaxAppAttempts is hardcoded to
1.
{code:java}
// Set Tez Sessions to not retry on AM crashes if recovery is disabled
if (!amConfig.getTezConfiguration().getBoolean(
TezConfiguration.DAG_RECOVERY_ENABLED,
TezConfiguration.DAG_RECOVERY_ENABLED_DEFAULT)) {
appContext.setMaxAppAttempts(1);
}
{code}
I think it is better to keep it configurable (Even when DAG recovery is false)
by remove this piece of code since the *appContext* object have already set the
*setMaxAppAttempts* to *TEZ_AM_MAX_APP_ATTEMPTS*.
