Hello Bright Sparks,
I was using Spark 1.3.0 to push data out to Parquet files. They have been
working great, super fast, easy way to persist data frames etc.
However I just swapped out Spark 1.3.0 and picked up the tarball for 1.3.1.
I unzipped it, copied my config over and then went to read one of my parquet
files from the last release when I got this:
java.lang.NoSuchFieldError: NO_FILTER

org.apache.spark.sql.parquet.ParquetRelation2$MetadataCache$$anonfun$refresh$6.apply(newParquet.scala:299)

I did some googling, it appears there were some changes to the Parquet file
format.
I found a reference to an option:
sqlContext.setConf("spark.sql.parquet.useDataSourceApi", "false")
Which I tried, but I got the same error (slightly different cause though).
java.lang.NoSuchFieldError: NO_FILTER

at org.apache.spark.sql.SQLContext.parquetFile(SQLContext.scala:542)
I presume its not just me, anyone else come across this ?
Any suggestions how to work around it ? can I set an option like
"old.parquet.format" or something ?
