------------------------------------
Summary: concurrency add jars cause hiveserver2 sys cpu to high
Key: HIVE-25474
URL: https://issues.apache.org/jira/browse/HIVE-25474
Project: Hive
Issue Type: Improvement
Components: Hive, HiveServer2
Affects Versions: 3.1.2
Reporter: guangbao zhao
Fix For: 3.1.2
Attachments:

In the Linux environment, when there are multiple concurrent add jars through
HiveCli or JDBC, the system cpu will increase. The currently used
FileUtil.chmod(dest, "ugo+rx", true); method is used for file authorization,
However, in jdk7+, can use Files.setPosixFilePermissions(path, perms); for file
authorization. The performance is seventy to eighty times that of the above.
Why not apply this method?
