setLocalResources

public TezClient.TezClientBuilder setLocalResources(Map<String,org.apache.hadoop.yarn.api.records.LocalResource> localResources)

setCredentials

public TezClient.TezClientBuilder setCredentials(org.apache.hadoop.security.Credentials credentials)

Setup security credentials

Parameters:

credentials - Set security credentials to be used inside the app master, if needed.

If the staging directory is on a file system for which credentials cannot be obtained or for any credentials needed by user code running inside the App Master, credentials must be supplied by the user. These will be used by the App Master for the next DAG.
In session mode, credentials, if needed, must be set before calling start()

Returns:

the current builder
