             Summary: SnappyCompressionCodec init exception handling masks important error information
                 Key: SPARK-10566
                 URL: https://issues.apache.org/jira/browse/SPARK-10566
             Project: Spark
          Issue Type: Bug
          Components: Input/Output
    Affects Versions: 1.5.0
            Reporter: Daniel Imfeld
            Priority: Minor




The change to always throw an IllegalArgumentException when failing to load in SnappyCompressionCodec (CompressionCodec.scala:151) throws away the description from the exception thrown, which makes it really difficult to actually figure out what the problem is:

: java.lang.IllegalArgumentException
	at org.apache.spark.io.SnappyCompressionCodec.<init>(CompressionCodec.scala:151)
	at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

Removing this try...catch I get the following error, which actually gives some information about how to fix the problem:

: java.lang.UnsatisfiedLinkError: no snappyjava in java.library.path
	at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1864)
	at java.lang.Runtime.loadLibrary0(Runtime.java:870)
	at java.lang.System.loadLibrary(System.java:1122)
	at org.xerial.snappy.SnappyLoader.loadNativeLibrary(SnappyLoader.java:178)
	at org.xerial.snappy.SnappyLoader.load(SnappyLoader.java:152)


A change to initialize the IllegalArgumentException with the value of e.getMessage() would be great, as the current error without any description just leads to a lot of frustrating guesswork.
