Minor Description
When hive.default.fileformat is other kinds of file types, create textfile table cause a serde error.
We should take the default type of textfile and sequencefile both as org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe.
set hive.default.fileformat=orc;
create table tbl( i string ) stored as textfile;
desc formatted tbl;
Serde Library org.apache.hadoop.hive.ql.io.orc.OrcSerde
InputFormat org.apache.hadoop.mapred.TextInputFormat
OutputFormat org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat
set hive.default.fileformat=orc;
create table tbl stored as textfile
as
select 1
It failed because it used the wrong SERDE
Caused by: java.lang.ClassCastException: org.apache.hadoop.hive.ql.io.orc.OrcSerde$OrcSerdeRow cannot be cast to org.apache.hadoop.io.BytesWritable
