Olivier Delalleau updated HDFS-8761:
------------------------------------
Description:
I'm periodically seeing errors like the one below output by the HDFS daemon
(started with start-dfs.cmd). This is with the default settings for data
location (=not specified in my hdfs-site.xml). I assume it may be fixable by
specifying a path with the drive letter in the config file, however I haven't
be able to do that (see
http://stackoverflow.com/questions/31353226/setting-hadoop-tmp-dir-on-windows-gives-error-uri-has-an-authority-component).
