lazyStartProducer
default HdfsEndpointBuilderFactory.AdvancedHdfsEndpointProducerBuilder lazyStartProducer(boolean lazyStartProducer)
Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. The option is a: <code>boolean</code> type. Default: false Group: producer (advanced)- Parameters:
lazyStartProducer
- the value to set- Returns:
- the dsl builder

splitStrategy
default HdfsEndpointBuilderFactory.AdvancedHdfsEndpointProducerBuilder splitStrategy(String splitStrategy)
In the current version of Hadoop opening a file in append mode is disabled since it's not very reliable. So, for the moment, it's only possible to create new files. The Camel HDFS endpoint tries to solve this problem in this way: If the split strategy option has been defined, the hdfs path will be used as a directory and files will be created using the configured UuidGenerator. Every time a splitting condition is met, a new file is created. The splitStrategy option is defined as a string with the following syntax: splitStrategy=ST:value,ST:value,... where ST can be: BYTES a new file is created, and the old is closed when the number of written bytes is more than value MESSAGES a new file is created, and the old is closed when the number of written messages is more than value IDLE a new file is created, and the old is closed when no writing happened in the last value milliseconds. The option is a: <code>java.lang.String</code> type. Group: advanced- Parameters:
splitStrategy
- the value to set- Returns:
- the dsl builder
