replace files with move when using pig on HDFS

Image
0 I have a process which moves files to a processing folder with a pig script as MapReduce2 task in part of a hadoop workflow. I have seen copies fail recently resulting in a partial move of the files. When the job then next re-runs there is an error as the pig script will try to move the file file again but as there is a partial of the file at the target location it will fail.

Creating a simple android app for receiving bluetooth strings?

1 I have an Arduino sketch that sends some string via Bluetooth module (I'm using HC-06) and everything works great, tested it out in PuTTY. Now. I'm new to Android developing and can't seem to find any good tutorial or piece of code that would wait for data from Bluetooth and print it to a textbox. Some are either outdated or are only about connecting and disconnecting from Bluetooth and seem to differ one from another. Or either there are huge amount of code with barely information or only snippets without notes where they go or what they are supposed to do. android bluetooth share | improve this question asked Nov 20 at 17:07
