Thejas M Nair commented on HIVE-5486:
-------------------------------------
But this section in old code in HiveSessionImplwithUGI.java was changing the
scratch dir from "/tmp/scratchdir" to "/tmp/scratchdir-username" . So the first
user (say user1) should create dir "/tmp/scratchdir-user1" , and a different
user2 should create "/tmp/scratchdir-user2" . Are you saying that logic wasn't
working ?
{code}
141
// Append the user name to temp/scratch directory path for each impersonated
user
142
private void setUserPath(String userName) {
143
for (HiveConf.ConfVars var: HiveConf.userVars) {
144
String userVar = getHiveConf().getVar(var);
145
if (userVar != null) {
146
// If there's a path separator at end then remove it
147
if (userVar.endsWith(File.separator)) {
148
userVar = userVar.substring(0, userVar.length()-2);
149
}
150
getHiveConf().setVar(var, userVar + "-" + userName);
151
}
152
}
153
}

> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.11.0, 0.12.0

>
> With impersonation enabled, the same base directory is used by all
> sessions/queries. For a new deployment, this directory gets created on first
> invocation by the user running that session. This would cause directory
> permission conflict for other users.
> HiveServer2 should create the base scratch dirs if it doesn't exist.
