Hitesh Shah commented on TEZ-3085:
----------------------------------
>From DAGAppMaster.java:
{code}
if (getConfig().getBoolean(TezConfiguration.TEZ_AM_CREDENTIALS_MERGE,
TezConfiguration.TEZ_AM_CREDENTIALS_MERGE_DEFAULT)) {
LOG.info("Merging AM credentials into DAG credentials");
dagCredentials.mergeAll(amCredentials);
}
{code}
This is true by default and in turn, these credentials are used when launching the task containers.
Can you provide logs/a concrete case of where this is not working.
> In session mode, the credentials passed via the Tez client constructor is not available
to all the tasks
