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
> Size. WAL Files (bytes) in regionserver status page displays negative values
