FLUME-2950. ReliableSpoolingFileEventReader.rollCurrentFile is broken
FLUME-2939 introduced a Java 7 API (nio.file) to
ReliableSpoolingFileEventReader. However, the committed patch breaks
rollCurrentFile() on Windows machines. File rename might be not atomic,
in such cases, and under the assumption that the rolled file and the
current file store the same data, Flume only logs a warning and does not
assume that the user broke the contract that the spooling directory
source demands.
In order to determine whether the files store the same data, we used the
com.google.common.io.Files.equal() method. However, FLUME-2939 uses
java.nio.file.Files.isSameFile() which has different semantics.
Consequently, this relaxation does not hold anymore. In addition,
TestSpoolingFileLineReader.testDestinationExistsAndSameFileWindows
fails. This patch brings back the old check using Files.equal().
