Aakash,
Here is a code snippet for the keys.
val accessKey = “---"
val secretKey = “---"
val hadoopConf = sc.hadoopConfiguration
hadoopConf.set("fs.s3a.access.key", accessKey)
hadoopConf.set("fs.s3a.secret.key", secretKey)
hadoopConf.set("spark.hadoop.fs.s3a.access.key",accessKey)
hadoopConf.set("spark.hadoop.fs.s3a.secret.key",secretKey)
val df =
sqlContext.read.parquet("s3a://aps.optus/uc2/BI_URL_DATA_HLY_20170201_09.PARQUET.gz")
df.show
df.count
When we do the count, then the error happens.
Thanks,
Ben
