Updates a hadoop map reduce job. Returns the output collection id in the data field of the response if successfully queued to run. If you change the timeToRun a job can be rescheduled.
A detailed guide to creating plugins. A simple web-based utility is available for for uploading JARs ( and other files)managing jobs. |
Authentication
Required, see Auth - Login.
...
frequencyToRun (required)
How often the job should be ran, either: NONE, HOURLY, DAILY, WEEKLY, MONTHLY. This will cause the job to get resubmitted after running, use NONE if you only want the job to run once.
...
query (required)
The mongo or JSON query to use to get the jobs data. {} is a blank query or you can submit null. See Custom - Schedule Job for more information about this query's format, or see the Hadoop Plugin Guide for more information.
inputcollection (required)

You can submit DOC_METADATA to get the documents table the documents metadata, DOC_CONTENT to get the document contents, or grab a previous map reduce jobs results table in your communities by submitting its id or title (must be a member of that community).
outputKey (required)
The classpath for the map reduce output format key usually org.apache.hadoop.io.Text
outputValue (required)
The classpath for the map reduce output format value usually org.apache.hadoop.io.IntWritable
json (optional)
Current you can pass a json object in containing any custom arguments you want passed in to the map reduce job at runtime, these arguments will be available in the config file in your mapper/reducer
format: { "arguments":"any string you want here" }
