It's a good practices to specify the JIRA number in the git commit log to keep the trace of the commit with the task information. It's quite useful when you need to merge the patches between different branch by grabbing the commits with the JIRA number.
I just went through the recent commit of iotdb, there is only some PRs[1] has the JIRA number , but there is no commits log specify the JIRA number. [1]https://github.com/apache/incubator-iotdb/pull/17 Willem Jiang Twitter: willemjiang Weibo: 姜宁willem
