[jira] [Created] (ACCUMULO-3867) Monitor updates lastRecalc value
in an unsafe manner
Josh Elser created ACCUMULO-3867:
------------------------------------
Summary: Monitor updates lastRecalc value in an unsafe manner
Key: ACCUMULO-3867
URL: https://issues.apache.org/jira/browse/ACCUMULO-3867
Project: Accumulo
Issue Type: Bug
Components: monitor
Affects Versions: 1.7.0
Reporter: Josh Elser
Assignee: Josh Elser
Priority: Trivial
Fix For: 1.7.1, 1.8.0
Monitor.fetchData does the following at the end of the method
{code}
} finally {
synchronized (Monitor.class) {
fetching = false;
lastRecalc.set(currentTime);
}
}
{code}
{{lastRecalc}} is a {{static long}} which is not guaranteed to be accurate across threads.
