It won't work well when Primary key is alpha numeric. I think data will be skewed or won't
come back as expected creating non-balanced split files.
Specify different numeric index as Split key if numeric primary key is not present.

Subject: sqoop import for UUID(primary key)

Hi,

In Sqoop If i am having primary key (Number value) and number of parallel task then it will
work (max-min/number of task), to pull the data from table to hdfs.

suppose if i have the primary key as UUID(alpha numeric value), how the load will be distributed.

Thank you for your help.
