Subject Re: 0.7 problem on cygwin
Date Wed, 27 Oct 2010 20:25:21 GMT
Sorry for my bad english.

In bootstrup cassandra send full file path between nodes, So for example win
node deside send value-e-27-Data.db file to unix node(cygwin in you case).
Unix node receive full file path of file "value-e-27-Data.db" on win node
i.e.

F:\cassandra\7.0\data\test_1\value-e-27-Data.db

>From this path cassandra detect column family(value), and keyspace(test_1).
It use for this  File.separatorChar(
http://download.oracle.com/javase/1.4.2/docs/api/java/io/File.html). So, as
on unix File.separatorChar="/", but file path have "\" as filepath
separator, you got assertion


Here is code from org\apache.cassandra.io.sstable.Descriptor.java with cause
assertion

    /**
     * @see #fromFilename(File directory, String name)
     */
    public static Descriptor fromFilename(String filename)
    {
        int separatorPos = filename.lastIndexOf(File.separatorChar);
        assert separatorPos != -1 : "Filename must include parent
directory.";
        File directory = new File(filename.substring(0, separatorPos));
        String name = filename.substring(separatorPos+1, filename.length());
        return fromFilename(directory, name).left;
    }



On linux or systems with the same File.separatorChar all ok. This behaivour
only when you bootsatrap on load balance. In initial cluster all ok too,
because no stream between nodes
