column Data issue after import

SamPatil — Fri, 16 Sep 2022 09:51:43 GMT

Hi All,

We are using Oracle as source to extract data using sqoop, In source table(Oracle) there is one column with data type RAW, whose data is getting changed after extracting data (adding to HDFS).

Below is sample data from Source column and target columns after sqoop import,

Issue is :- Adding extra space.

Source data

A567B4CDAA7109CE31A24DC1F1C585D4B115BBFBF82F49EAB748792E25AE0C767FDC89AFC984D862E579F3F1D8F9B8AEC55CBD8F0AF70F49CE77714AEB99AE5732DCAA0B3A5C71CE6F8DDD18E8CE82D24DF2367D4AD5C85C92FD0551610A241FAD4E69AF243FBAB432CDA011100FD4BD5BD99EB93639FB6F052F7B2849CBF730401F2C30FE6C4BD9A2D0D3667D07B3527AEEFDC0DC2B250F52BFE4A590C9833B356431C406E765B522D6232E8BB1B353

Not sure if one has to handle RAW field through an extra step of transforming into hexadecimal format per below statement in oracle docs.

* RAW binary data in delimited text files must be encoded in hexadecimal.

However, I am curious to see if any solution for this issue.

Hi All,

It got resolved. below is the solutions of same.

Columns which are used in import statement are having \n i.e. new line in column data. This new line was separating column data into two rows while importing data. Sqoop is considering \n character as a new line separator, which is a default setting of sqoop import. We have avoided \n character in column data using parameter --hive-delims-replacement " " .

Thanks,

Samadhan
