Hi Nick, Which version of Hadoop are you using with Spark? I spotted an issue with the built-in GzipDecompressor while doing something similar with Hadoop 1.0.4, all my Gzip files were valid and tested yet certain files blew up from Hadoop/Spark.
The following JIRA ticket goes into more detail https://issues.apache.org/jira/browse/HADOOP-8900 and it affects all Hadoop releases prior to 1.2.X MC *Michael Cutler* Founder, CTO *Mobile: +44 789 990 7847Email: mich...@tumra.com <mich...@tumra.com>Web: tumra.com <http://tumra.com/?utm_source=signature&utm_medium=email>* *Visit us at our offices in Chiswick Park <http://goo.gl/maps/abBxq>* *Registered in England & Wales, 07916412.
