Hi Everyone,
Environment used: Datastax Enterprise 4.8.3 which is bundled with Spark
1.4.1 and scala 2.10.5.
I am using Dataframes to query Cassandra, do processing and store the
result back into Cassandra. The job is being submitted using spark-submit
on a cluster of 3 nodes. While doing so I get three WARN messages:
WARN 2016-01-28 19:08:18 org.apache.spark.scheduler.TaskSetManager: Lost
task 99.0 in stage 2.0 (TID 107, 10.2.1.82): java.io.InvalidClassException:
org.apache.spark.sql.types.TimestampType$; unable to create instance
Caused by: java.lang.reflect.InvocationTargetException
Caused by: java.lang.UnsupportedOperationException: tail of empty list
For example, if I am running the same job, for the same input set of data,
say 20 times,
- 11 times it will run successfully without any WARN messages
- 4 times it will run successfully with the above messages
- 6 times it will run successfully by randomly giving one or two of the
exceptions above
In all the 20 runs, the output data is coming as expected and there is no
error in that. My concern is, why is it not giving these messages every
time I do a spark-submit but only at times. Also, the stack trace does not
point to any specific point in my line of code. Full stack trace is as
follows. Please let me know if you need any other information
WARN 2016-01-28 19:08:24 org.apache.spark.scheduler.TaskSetManager: Lost
task 188.0 in stage 16.0 (TID 637, 10.2.1.82):
