Before your reply I've rebooted the node after that it's run well.
Now I can see some issue(Port running on other Node) again when I'm running the COMPUTE STATS command on Impala.
1.I have a table with old Parquet data.
2.Now I have added parquet data with New data types(INT TO STRING) for the same columns.
3.I have created new table in the same location with new schema
(Impala > CREATE EXTERNAL TABLE database.table2 like parquet '/home/output/university/client=england/campaign=second/details=students/part-r-00111-5fce6c4d-784e-457f-9a01-aa6d6ec1187c.snappy.parquet';
Impala > SHOW CREATE TABLE table2;
Then Ive created tablw with table2 schema)
4. /home/output/university/client=england/campaign=second/details=students/part-r-00111-5fce6c4d-784e-457f-9a01-aa6d6ec1187c.snappy.parquet' has an incompatible Parquet schema for column 'mobistat.psrvoicecdma.systemid'. Column type: STRING, Parquet schema:
optional int32 systemid [i:22 d:1 r:0]
please help me out in this.
