I am running Spark on Windows. When I try to view the Executor logs in the UI
I get the following error:
HTTP ERROR 500
Problem accessing /logPage/. Reason:

Looking at the source code for
org.apache.spark.deploy.worker.ui.LogPage.getLog reveals the following:
- At line 141 the constructor of java.net.URI is called with the path to
the log directory as a String argument. This string
(".\work/app-20160129154716-0038/2/" in example above) contains a backslash,
which is an illegal character for the URI constructor.
- The component of the path containing the backslash is created at line 71
by calling the getPath method on a java.io.File object. Because it is
running on Windows it uses the default Windows file separator, which is a
backslash.
I am using Spark 1.5.1 but the source code appears unchanged in 1.6.0.
I haven't been able to find an open issue for this but if there is one could
possibly submit a pull request for it.
