Mark Grover created SPARK-11794: ----------------------------------- Summary: Improve error message when HDFS/S3 access is misconfigured when using Parquet Key: SPARK-11794 URL: https://issues.apache.org/jira/browse/SPARK-11794 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 1.6.0 Reporter: Mark Grover
I had a scenario where I was accessing HDFS from a node set up for secure HDFS access. However, my actual HDFS cluster was set up in non-secure mode. This mismatch of configuration didn't allow me to access HDFS. However, when running a Spark app on some Parquet data on the said inaccessible HDFS, one gets a message like this: {code} java.lang.AssertionError: assertion failed: No predefined schema found, and no Parquet data files or summary files found under {code} Which is very misleading. And, I am not the only one this has happened to. See SPARK-9565 for another similar situation. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
