------------------------------
Assignee: Daniel Imfeld
> 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
> Assignee: Daniel Imfeld
> Priority: Minor
> Fix For: 1.6.0, 1.5.1
>
>
> 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.
