as a consumer, if it's a file, it just reads the file, otherwise if it represents a directory it scans all the file under the path satisfying the configured pattern. All the files under that directory must be of the same type.
as a producer, if at least one split strategy is defined, the path is considered a directory and under that directory the producer creates a different file per split named using the configured UuidGenerator.

Note
When consuming from hdfs then in normal mode, a file is split into chunks, producing a message per chunk. You can configure the size of the chunk using the chunkSize option. If you want to read from hdfs and write to a regular file using the file component, then you can use the fileMode=Append to append each of the chunks together.

Name	Default Value	Description
`overwrite`	`true`	The file can be overwritten
`append`	`false`	Append to existing file. Notice that not all HDFS file systems support the append option.
`bufferSize`	`4096`	The buffer size used by HDFS
`replication`	`3`	The HDFS replication factor
`blockSize`	`67108864`	The size of the HDFS blocks
`fileType`	`NORMAL_FILE`	It can be SEQUENCE_FILE, MAP_FILE, ARRAY_FILE, or BLOOMMAP_FILE, see Hadoop
`fileSystemType`	`HDFS`	It can be LOCAL for local filesystem
`keyType`	`NULL`	The type for the key in case of sequence or map files. See below.
`valueType`	`TEXT`	The type for the key in case of sequence or map files. See below.
`splitStrategy`		A string describing the strategy on how to split the file based on different criteria. See below.
`openedSuffix`	`opened`	When a file is opened for reading/writing the file is renamed with this suffix to avoid to read it during the writing phase.
`readSuffix`	`read`	Once the file has been read is renamed with this suffix to avoid to read it again.
`initialDelay`	`0`	For the consumer, how much to wait (milliseconds) before to start scanning the directory.
`delay`	`0`	The interval (milliseconds) between the directory scans.
`pattern`	`*`	The pattern used for scanning the directory
`chunkSize`	`4096`	When reading a normal file, this is split into chunks producing a message per chunk.
`connectOnStartup`	`true`	Camel 2.9.3/2.10.1: Whether to connect to the HDFS file system on starting the producer/consumer. If `false` then the connection is created on-demand. Notice that HDFS may take up till 15 minutes to establish a connection, as it has hardcoded 45 x 20 sec redelivery. By setting this option to `false` allows your application to startup, and not block for up till 15 minutes.
`owner`		Camel 2.13/2.12.4: The file owner must match this owner for the consumer to pickup the file. Otherwise the file is skipped.
