-------------------------------
Summary: Potential race condition in startLocalizer when using
LinuxContainerExecutor
Key: YARN-2701
URL: https://issues.apache.org/jira/browse/YARN-2701
Project: Hadoop YARN
Issue Type: Bug
Reporter: Xuan Gong
Assignee: Xuan Gong
When using LinuxContainerExecutor do startLocalizer, we are using native code
container-executor.c.
{code}
if (stat(npath, &sb) != 0) {
if (mkdir(npath, perm) != 0) {
{code}
We are using check and create method to create the appDir under /usercache. But
if there are two containers trying to do this at the same time, race condition
may happen.
