Subject [jira] [Commented] (HBASE-15722) Size. WAL Files (bytes) in regionserver status page displays negative values

Samir Ahmic commented on HBASE-15722:
-------------------------------------

Same thing with hlogFileSize in jmx metrics it is negative number. This is defaultWALProvider,
i did not change default config. So far i have tracked this to AbstractFSWAL.java:
{code}
561         this.totalLogSize.addAndGet(-this.fs.getFileStatus(p).getLen());
{code}
This is how we get negative value. What i'm checking  now is why {code}totalLogSize{code}
end up being negative
