Hi,
It seems koalas.DataFrame can't be displayed in terminal yet as in
https://github.com/databricks/koalas/issues/150 and the work around is
to convert it to pandas DataFrame.
Thanks,
Manu Zhang

You may try
`sparkContext.hadoopConfiguration().set("mapred.max.split.size",
"33554432")` to tune the partition size when reading from HDFS.

Has anyone seen this kind of error before ? I could provide more
information if needed.
Thanks,

Is your application using Spark SQL / DataFrame API ? Is so, please try setting
spark.sql.files.maxPartitionBytes
to a larger value which is 128MB by default.
Thanks,

Have you tried adding Encoder for columns as suggested by Jungtaek Lim ？

Hi,
It's added since Spark 2.3.0.

Hi Fawze,
A) The file permission is currently hard coded to 770 (
https://github.com/apache/spark/blob/branch-2.3/core/src/main/scala/org/apache/spark/scheduler/EventLoggingListener.scala#L287
).
B) I think add all users (including UI) to the group like Spark will do.

able to see applications once changing file permissions to 777.

Manu Zhang
