A feed can have multiple source and target clusters. If the type of cluster is not specified then the cluster is not considered for replication. Validity of a feed on cluster specifies duration for which this feed is valid on this cluster. Retention specifies how long the feed is retained on this cluster and the action to be taken on the feed after the expiry of retention period. The retention limit is specified by expression frequency(times), ex: if feed should be retained for at least 6 hours then retention's limit="hours(6)". The field partitionExp contains partition tags. Number of partition tags has to be equal to number of partitions specified in feed schema. A partition tag can be a wildcard(*), a static string or an expression. Atle
ast one of the strings has to be an expression. Location specifies where the feed is available on this cluster. This is an optional parameter and path can be same or different from the global locations tag value ( it is mentioned outside the clusters tag ) . This tag provides the user to flexibility to have feed at different locations on different clusters. If this attribute is missing then the default global location is picked from the feed definition. Also the individual location tags data, stats, meta are optional.</p><div class="source"><pre class="prettyprint">

A feed should at least define the location for type data, which specifies the HDFS path pattern where the feed is generated periodically. ex: type="data" path="/projects/TrafficHourly/${YEAR}-${MONTH}-${DAY}/traffic" The granularity of date pattern in the path should be atleast that of a frequency of a feed. Other location type which are supported are stats and meta paths, if a process references a feed then the meta and stats paths are available as a property in a process.</p><div class="source"><pre class="prettyprint">

A workflow is a directed acyclic graph(DAG) which defines the job for the workflow engine. A process definition defines the configurations required to run the workflow job. For example, process defines the frequency at which the workflow should run, the clusters on which the workflow should run, the inputs and outputs for the workflow, how the workflow failures should be handled, how the late inputs should be handled and so on.</p><p>The different details of process are:</p></div><div class="section"><h5>Name<a name="Name"></a></h5><p>Each process is identified with a unique name

Cluster definition for the cluster name gives the end points for workflow execution, name node, job tracker, messaging and so on. Each cluster inturn has validity mentioned, which tell the times between which the job should run on that specified cluster. Syntax:</p><div class="source"><pre class="prettyprint">

If timeout is not specified, falcon computes a default timeout for a process based on its frequency, which is six times of the frequency of process or 30 minutes if computed timeout is less than 30 minutes.</p><div class="source"><pre class="prettyprint">

For example, hours(1) defines the frequency as hourly, days(7) defines weekly frequency. The values for timeunit can be minutes/hours/days/months and the frequency number should be a positive integer > 0. Syntax:</p><div class="source"><pre class="prettyprint">

Start time and end time are timestamps defined in yyyy-MM-dd'T'HH:mm'Z' format and should always be in UTC. Timezone is used to compute the next instances starting from start time. The workflow will start at start time and end before end time specified on a given cluster. So, there will not be a workflow instance at end time.

The workflow job will start executing only after the schedule time and when all the inputs are available. There can be 0 or more inputs and each of the input maps to a feed. The path and frequency of input data is picked up from feed definition. Each input should also define start and end instances in terms of <a href="./FalconDocumentation.html">EL expressions</a> and can optionally specify specific partition of input that the workflow requires. The components in partition should be subset of partitions defined in the feed.</p><p>For each input, Falcon will create a property with the input name that contains th
