-------------------------------------
Summary: Slider JsonSerDeser can use readFully instead of read to
avoid " Read finished prematurely"
Key: SLIDER-1234
URL: https://issues.apache.org/jira/browse/SLIDER-1234
Project: Slider
Issue Type: Bug
Components: core
Affects Versions: Slider 0.92
Reporter: Prabhu Joseph
Slider JsonSerDeser uses FSDataInputStream#read() inside load method which
fails sometimes with "Read finished prematurely" when there is a data loss for
the data sent over the socket.
Better to use readFully() which can avoid this.
