[jira] [Created] (HDFS-13586) Fsync fails on directories on Windows
Lukas Majercak created HDFS-13586:
-------------------------------------
Summary: Fsync fails on directories on Windows
Key: HDFS-13586
URL: https://issues.apache.org/jira/browse/HDFS-13586
Project: Hadoop HDFS
Issue Type: Bug
Components: datanode, hdfs
Reporter: Lukas Majercak
Assignee: Lukas Majercak
HDFS-11915 added a fsync call on DataNode's rbw directory on the first hsync() call. IOUtils.fsync first tries to get a FileChannel on the directory using FileChannel.open(READ). This call fails on Windows for any directory and throws an AccessDeniedException, see discussion here: [http://mail.openjdk.java.net/pipermail/nio-dev/2015-May/003140.html].
