Latin fonts not appearing properly.
I am already controlled my docker container side , core.py and supersetconfig.py in there UTF-8
Sometimes with office 365 is better not opening the csv file and use the
import csv option
Or you could try different encoding when you import it.

You can convert excel to csv by using transformation with just two steps inside:
Microsoft Excel input - it should read rows from your excel file
Text file output - it saves rows from step 1 to csv file
Using Sqoop I’ve successfully imported a few rows from a table that has a BLOB column.Now the part-m-00000 file contains all the records along with BLOB field as CSV.
Questions:
1) As per doc, knowledge about the Sqoop-specific format can help to read those blob records.
So , What does the Sqoop-specific format means ?
2) Basically the blob file is .gz file of a text file containing some float data in it. These .gz file is stored in Oracle DB as blob and imported into HDFS using Sqoop. So how could I be able to get back those float data from HDFS file.
Any sample code will of very great use.
I see these options.
Sqoop Import from Oracle directly to hive table with a binary data type. This option may limit the processing capabilities outside hive like MR, pig etc. i.e. you may need to know the knowledge of how the blob gets stored in hive as binary etc. The same limitation that you described in your question 1.
Sqoop import from oracle to avro, sequence or orc file formats which can hold binary. And you should be able to read this by creating a hive external table on top of it. You can write a hive UDF to decompress the binary data. This option is more flexible as the data can be processed easily with MR as well especially the avro, sequence file formats.
Hope this helps. How did you resolve?
