Subject Spark failed while trying to read parquet files
Date Fri, 07 Aug 2015 22:20:44 GMT
Hi all,

I have a partitioned parquet table (very small table with only 2
partitions). The version of spark is 1.4.1, parquet version is 1.7.0. I
applied this patch to spark [SPARK-7743] so I assume that spark can read
parquet files normally, however, I'm getting this when trying to do a
simple `select count(*) from table`,

```org.apache.spark.SparkException: Job aborted due to stage failure: Task
29 in stage 44.0 failed 15 times, most recent failure: Lost task 29.14 in
stage 44.0: java.lang.NullPointerException

Has anybody seen this before?

Thanks
