Setting Parameters for a Workflow or SHELL-type of Task¶

This section shows how to set the parameters when you configure a workflow or task.

Available Options for Parameters¶

You can specify constants, system variables, or custom variables for a parameter.

See Supported System Variables for the system variables that can be used.

Procedure¶

When you are in the workflow or task configuration panel, click Parameter Settings at the right edge of the panel.
For each parameter that you use, provide the value using the key=value format. If you have multiple parameters to define, list each parameter in a new line, for example:

key1=value1
key2=value2

The value can be a single value, or an array of values.

Example: Using Parameters in SHELL script¶

The following shows an example where parameters are used in the SHELL script.

java -cp ide.sdk-0.1.3.jar com.envision.dataplatform.C2R.C2RBeelineUtil -i
${inputPath}  -o ${outputPath} -ot ${outputTableName} -ca ${columnAll} -cm
${columnMust} -cs ${columnSelected} -g ${group_name} -h "${HIVE_JDBC}" -u
${unix_timestamp} -z ${time_zone}

You can assign values for the parameters as per the following:

inputPath=/user/hive/warehouse/xiaoxiao_product_db.db/input
outputPath=/tmp/xiaoxiao/output
outputTableName=2018_07_31
columnAll=projectid,deviceid,updatetime,envi_monitor_pm1,envi_monitor_pm25
columnMust=projectid,deviceid,updatetime,
columnSelected=envi_monitor_pm1,envi_monitor_pm25
time_zone=Asia/Shanghai
