Mark Payne commented on NIFI-1165:
----------------------------------
I attached a patch for TailFile. The processor was leaking the RandomAccessFile
when stopped and started, which caused the unit tests to fail in the setup()
method. After addressing that issue, I needed to also fix the timestamp so that
it works with file systems that use a second-precision Last Modified Date as
well as those that use millisecond-precision. I also found that
RandomAccessFile will lock the file in Windows, so that the log file being
written to couldn't be rolled over; this was addressed by changing from a
RandomAccessFile to a FileChannel.

> I tested with two separate Windows 8 machines and get the same errors when
> building master. There are errors in PutHDFSTest, TestRouteText and
> TestTailFile
> PutHDFSTest fails on lines 186 and 198.
> The output for the TestRouteText and TestTailFile:
> TestRouteText.testJson:655 expected:<7> but was:<0>
> TestRouteText.testXml:691 expected:<1> but was:<0>
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.testRolloverAfterHavingReadAllData:277 expected:<2> but was:<0>
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestTailFile.setup:61 null
> TestHDFS is failing due to: "java.io.IOException: Could not locate executable
> null\bin\winutils.exe in the Hadoop binaries."
> TestRouteText is actually failing due to attempting to take into account
> Windows by using "System.lineSeparator()" when traversing a file that is
> checked into git using "\n" line separators.
> TestTailFile I believe is failing due to the processor holding a lock on the
> file while the file is trying to be rolled over. In order to manually test
> it, I ran NiFi and started tailing a file. When I tried to rename it (like a
> server rolling over a file would) it told me it was in use by Java.
> I already have a fix for TestRouteText, Oleg and I are working on HDFS, and
> Mark is working on TailFile
