tez.am.commit-all-outputs-on-dag-success true Boolean value. Determines when the final outputs to data sinks are committed. Commit is an output specific operation and typically involves making the output visible for consumption. If the config is true, then the outputs are committed at the end of DAG completion after all constituent vertices have completed. If false, outputs for each vertex are committed after that vertex succeeds. Depending on the desired output visibility and downstream consumer dependencies this value must be appropriately chosen. Defaults to the safe choice of true. boolean false false false

Should be specified as a comma-separated of key-value pairs where each pair is defined as KEY=VAL e.g. "LD_LIBRARY_PATH=.,USERNAME=foo" These take least precedence compared to other methods of setting env.

Advanced configuration: Set the log level for all classes, along with a different level for some. e.g. DEBUG;org.apache.hadoop.ipc=INFO;org.apache.hadoop.security=INFO This sets the log level for all loggers to DEBUG, expect for the org.apache.hadoop.ipc and org.apache.hadoop.security, which are set to INFO Note: The global log level must always be the first parameter. DEBUG;org.apache.hadoop.ipc=INFO;org.apache.hadoop.security=INFO is valid org.apache.hadoop.ipc=INFO;org.apache.hadoop.security=INFO is not valid string false false false

Represents the maximum time in seconds for which a consumer attempt can report a read error against its producer attempt, after which the producer attempt will be re-run to re-generate the output. There are other heuristics which determine the retry and mainly try to guard against a flurry of re-runs due to intermittent read errors (due to network issues). This configuration puts a time limit on those heuristics to ensure jobs dont hang indefinitely due to lack of closure in those heuristics Expert level setting. integer false false false
tez.am.max.app.attempts 2 Int value. Specifies the number of times the app master can be launched in order to recover from app master failure. Typically app master failures are non-recoverable.

tez.am.preemption.max.wait-time-ms 60000 Int value. Time (in millisecs) that an unsatisfied request will wait before preempting other resources. In rare cases, the cluster says there are enough free resources but does not end up getting enough on a node to actually assign it to the job. This configuration tries to put a deadline on such wait to prevent indefinite job hangs. integer false false false
tez.am.preemption.percentage 10 Int value. Specifies the percentage of tasks eligible to be preempted that will actually be preempted in a given round of Tez internal preemption. This slows down preemption and gives more time for free resources to be allocated by the cluster (if any) and gives more time for preemptable tasks to finish. Valid values are 0-100. Higher values will preempt quickly at the cost of losing work. Setting to 0 turns off preemption. Expert level setting. integer false false false

Enables an idle session (not running any DAG) to hold on to a minimum number of containers to provide fast response times for the next DAG. integer false false false
tez.am.mode.session false Boolean value. Execution mode for the Tez application. True implies session mode. If the client code is written according to best practices then the same code can execute in either mode based on this configuration. Session mode is more aggressive in reserving execution resources and is typically used for interactive applications where multiple DAGs are submitted in quick succession by the same user. For long running applications, one-off executions, batch jobs etc non-session mode is recommended. If session mode is enabled then container reuse is recommended. boolean false false false

tez.container.max.java.heap.fraction 0.8 Double value. Tez automatically determines the Xmx for the JVMs used to run Tez tasks and app masters. This feature is enabled if the user has not specified Xmx or Xms values in the launch command opts. Doing automatic Xmx calculation is preferred because Tez can determine the best value based on actual allocation of memory to tasks the cluster. The value if used as a fraction that is applied to the memory allocated Factor to size Xmx based on container memory size. Value should be greater than 0 and less than 1. float false false false

tez.lib.uris null String value to a file path. The location of the Tez libraries which will be localized for DAGs. This follows the following semantics
  1. To use a single .tar.gz or .tgz file (generated by the tez build), the full path to this file (including filename) should be specified. The internal structure of the uncompressed tgz will be retained under $CWD/tezlib.
