In you examples , I noticed that the inserting statement is neccessary after
changed table schema.
I also tested as the following steps:
1. alter table column type(from int to long)
2. select * from table, then throw an excetpion :
Caused by: java.lang.NullPointerException
at
org.apache.spark.sql.execution.vectorized.WritableColumnVector.arrayData(WritableColumnVector.java:710)
but if I execute an insert statement succesfully after altering column type,
the select statement will be successful, i.e. the exception above will also
disappear.
So, it seems that we have to execute inserting statement after altering
statement. But i don't know why, if you do, please let me know, thank you.
