Manish Maheshwari commented on SPARK-9896:
------------------------------------------
I got the same error.
{code:java}
Exception in thread "main" java.lang.AssertionError: assertion failed: No
predefined schema found, and no Parquet data files or summary files found under
hdfs://nameservice1/user/hive/warehouse/abt.db/hvc_features_avg_3months.
at scala.Predef$.assert(Predef.scala:179)
$hdfs dfs -ls
hdfs://nameservice1/user/hive/warehouse/abt.db/hvc_features_avg_3months
ls: Permission denied: user=eksinad, access=READ_EXECUTE,
inode="/user/hive/warehouse/abt.db/hvc_features_avg_3months":hive:hive:drwxrwx--x
{code}
However I can select data from the table using Beeline using the same keytab as
what I use to submit spark job. Very strange
Also the error message from Spark is very misleading.
