Samuel Guo updated HAMA-86:
---------------------------
Description:
Let's discuss the generic load/save operation from/to other sources(such as,
FileSystem).
matrices in FileSystem may have different format, parsing of the file as a
matrix depends on the format.
we may need some methods like:
/**
* Save a matrix as file using specified OutputFormat.
*
* @param path
* the file path.
* @param format
* the format of the matrix.
* @return true if saved
* @throws IOException
*/
public boolean saveAsFile(Path filepath, OutputFormat format) throws
IOException;
/**
* Load a matrix from file
*
* @param path
* the file path.
* @param format
* the format of the matrix.
* @return true if saved
* @throws IOException
*/
public static Matrix loadFromFile(Path filepath, OutputFormat format) throws
IOException;
was:
we need a generic "pathname" class to identify the input & output.
"pathname" can contain two parts: one is scheme, such as HBASE or HDFS; one
will be the actual name, such as table name in HBase, filename in HDFS.
I've changed the description.
