[GitHub] [incubator-doris] xinghuayu007 opened a new issue #5577: [Bug] keytab file maybe not thread safe
xinghuayu007 opened a new issue #5577:
URL: https://github.com/apache/incubator-doris/issues/5577
**Describe the bug**
Thread A has a kerberos account: k_test1, Thread B has another kerberos account: k_test2。When they all broker load at the same time, they will create a keytab file to store the keytab file content. But if the file name is the same, the file content will be covered by another thread, which will cause the kerberos login in failed.
File name is generated by this rule.
`tmpFilePath = "/tmp/." + Long.toString(currentTime) + "_" + Integer.toString(randNumber);`
it is very low probability to generate the same file name, but in reality, it happened.
