-----------------------------------

Hello.

One of my customer is experiencing the same issue.
Currently, Cloudera CDH is used, and due to the bug, patch is required.

I wonder if this bug causes functional problems?
The patch is very careful because the site is very sensitive to patches.

Could you answer that?

 

안녕하세요. 

저희 사이트도 동일한 이슈가 발생하고 있습니다.
현재 Cloudera CDH를 이용하고 있으며, 해당 Bug로 인하여 Patch가 필요한
상태입니다.
궁금한 점은,,
 이 Bug로 인하여 기능적인 문제가 발생하는지에 대하여 궁금합니다.
사이트가 패치에 대해 매우 민감하므로 Patch가 조심스럽습니다.

혹시 답변해 주실수 있으신지요?
