--------------------------------------
Summary: shmem communication does not work if Ignite node and
Hadoop client running on behalf of different users
Key: IGNITE-679
URL: https://issues.apache.org/jira/browse/IGNITE-679
Project: Ignite
Issue Type: Bug
Components: hadoop
Affects Versions: sprint-3
Reporter: Ivan Veselovsky
Assignee: Ivan Veselovsky
Fix For: sprint-3
problem is that shmem native library loader uses global file lock
/tmp/igniteshmem.lock . Upon Ignite node start this lock is created by the
Ignite service user ("ignite"). When client starts, it tries to get "rws" lock
on this file, but fails because that file is typically not writable for the
client user. This permanently prevents the client from loading the native shmem
library, and, ans a consequence, shmem communication from working.
