Streamsx-hdfs

The operator **HDFS2FileSink** provides a new parameter **tempFile**.
The **tempFile** parameter specifies the name of the file that the operator writes to. When the file is closed the file is renamed to the final filename defined by the **file** parameter.

The **streamx.hdfs.toolkits-4.2.0** release delivers corrections for FileNotFoundException issue 100 and issue 90
The release has been created on a RedHad 7.5 linux server with
IBM Streams Version=**4.3.0.0** Build=20180725113900
This release fixed also divers deprecated hadoop functions.

The HDFS Toolkit has been improved to support the IBM Streams on Cloud.
A new pom.xml file download only the needed JAR libraries to build the toolkit.
The Hadoop JAR libraries are now integrated in the toolkit lib/ext directory.

The HDFS Toolkit has now a reconnection policy. It tries to reconnect to the HDFS when it fails
All operators have now 4 new parameters:
hdfsPassword
reconnectionPolicy
reconnectionBound
reconnectionInterval

It is now possible to submit an SPL application on IBM Streams Cloud without any
Hadoop client installation on Streams server.

A sample has been provided to describe the build and submit a SPL application with new
version of HDFS Toolkit.
