----------------------------------
Summary: UniformRangePartition cannot deal with unicode ranges
Key: TAJO-1004
URL: https://issues.apache.org/jira/browse/TAJO-1004
Project: Tajo
Issue Type: Bug
Reporter: Hyunsik Choi
Fix For: 0.9.0
UniformRangePartition plays a role to divide a given range into multiple sub
ranges. It is used for range shuffle.
When UniformRangePartition divides a range of text fields, it Internally
transforms arrays of bytes into unsigned integer. But, a byte represent -127 to
127, and unicode is out of range in byte representation. So, the current
approach can cause errors in this case.
