Name of the environment variable that holds the unique script operator ID in the user's transform function (the custom mapper/reducer that the user has specified in the query).
hive.script.operator.env.blacklist
- Default Value: hive.txn.valid.txns,hive.script.operator.env.blacklist
- Added In: Hive 0.14.0
By default all values in the HiveConf object are converted to environment variables of the same name as the key (with '.' (dot) converted to '_' (underscore)) and set as part of the script operator's environment. However, some values can grow large or are not amenable to translation to environment variables. This value gives a comma separated list of configuration values that will not be set in the environment when calling a script operator. By default the valid transaction list is excluded, as it can grow large and is sometimes compressed, which does not translate well to an environment variable.
hive.exec.compress.output
- Default Value:
false
- Added In: Hive 0.2.0
