templeton.port

The HTTP port for the main server.

templeton.hadoop.config.dir

The path to the Hadoop configuration.

Obsolete: templeton.jar

The path to the WebHCat jar file. (Not used in recent releases, so removed in Hive 0.14.0.)

templeton.libjars

Jars to add to the classpath.

templeton.override.jars

Jars to add to the HADOOP_CLASSPATH for all Map Reduce jobs. These jars must exist on HDFS.

templeton.override.enabled

Enable the override path in templeton.override.jars.

templeton.streaming.jar

The HDFS path to the Hadoop streaming jar file.

templeton.hadoop

The path to the Hadoop executable.

templeton.pig.archive

The path to the Pig archive.

templeton.pig.path

The path to the Pig executable.

templeton.hcat

The path to the HCatalog executable.

templeton.hive.archive

The path to the Hive archive.

templeton.hive.path

The path to the Hive executable.

templeton.hive.properties

Properties to set when running Hive (during job submission).  This is expected to be a comma-separated prop=value list. If some value is itself a comma-separated list, the escape character is '\' </description> (from Hive 0.13.1 onward).

To use it in a cluster with Kerberos security enabled, set hive.metastore.sasl.enabled=false and add hive.metastore.execute.setugi=true. Using localhost in metastore URI does not work with Kerberos security.

templeton.exec.encoding

The encoding of the stdout and stderr data.

templeton.exec.timeout

How long in milliseconds a program is allowed to run on the WebHCat box.

templeton.exec.max-procs

The maximum number of processes allowed to run at once.

templeton.exec.max-output-bytes

The maximum number of bytes from stdout or stderr stored in ram.

templeton.controller.mr.child.opts

Java options to be passed to WebHCat controller map task.

templeton.exec.envs

The environment variables passed through to exec.

templeton.zookeeper.hosts

ZooKeeper servers, as comma-separated host:port pairs.

templeton.zookeeper.session-timeout

ZooKeeper session timeout in milliseconds.

templeton.callback.retry.interval

How long to wait between callback retry attempts in milliseconds.

templeton.callback.retry.attempts

How many times to retry the callback.

templeton.storage.class

The class to use as storage.

templeton.storage.root

The path to the directory to use for storage.

templeton.hdfs.cleanup.interval

The maximum delay between a thread's cleanup checks.

templeton.hdfs.cleanup.maxage

The maximum age of a WebHCat job.

templeton.zookeeper.cleanup.interval

The maximum delay between a thread's cleanup checks.

templeton.zookeeper.cleanup.maxage

The maximum age of a WebHCat job.

templeton.kerberos.secret

The secret used to sign the HTTP cookie value. The default value is a random value. Unless multiple WebHCat instances need to share the secret the random value is adequate.

templeton.kerberos.principal

The Kerberos principal to used by the server. As stated by the Kerberos SPNEGO specification, it should be USER/${HOSTNAME}@{REALM}. It does not have a default value.

templeton.kerberos.keytab

The keytab file containing the credentials for the Kerberos principal.

MapReduce queue name where WebHCat map-only jobs will be submitted to. Can be used to avoid a deadlock where all map slots in the cluster are taken over by Templeton launcher tasks.

Versions: Hive 0.12.0 and later.

WebHCat controller job's Launch mapper's memory limit in megabytes. When submitting a controller job, WebHCat will overwrite mapreduce.map.memory.mb with this value. If empty, WebHCat will not set mapreduce.map.memory.mb when submitting the controller job, therefore the configuration in mapred-site.xml will be used.

Versions: Hive 0.14.0 and later.

Adds web server protection from clickjacking using X-Frame-Options header. The possible values are DENY, SAMEORIGIN, ALLOW-FROM <uri>.

Versions: Hive 3.0.0 and later.
